FormatException.  This bug has been fixed in JDK 1.1.4.  [Bug 4031620]

_________________
AWT COMPONENT BUG - In the Windows version of JDK 1.1.3, incorrect 
character codes from non-101 keyboards where being received, causing 
the incorrect generation of a KeyPressed/Release event.  This bug has 
been fixed in JDK 1.1.4.  [Bugs 4051910, 4053800]

__________________
AWT POPUP MENU BUG - Removing menus from PopupMenus on Solaris versions 
of JDK 1.1.2 and JDK 1.1.3 caused a core dump. This problem has been 
corrected in JDK 1.1.4.  [Bug 4054479]

__________
AWT IM BUG - In the Solaris version on the JDK 1.1.1, the IM status 
region was created inside of the AWT window and broke the layout of the 
window.  This bug has been fixed in JDK 1.1.4.  [Bug 4041569]

____________
AWT MENU BUG - In the Solaris version of the JDK 1.1.2 & JDK 1.1.3 a 
core dump would result when removing MenuItems from submenus on 
PopuMenus.  This bug has been fixed in JDK 1.1.4.  [Bug 4054479]

____________________
AWT MODAL DIALOG BUG - Calls to the hide() method in the Win32 version 
of JDK 1.1.3 does not always hide the modal dialog.  This is a 
regression from JDK 1.1.1.  This bug has been fixed in JDK 1.1.4 
[Bug 4068651]

______________
AWT CURSOR BUG - In JDK 1.1.3, Frame.setCursor sometimes didn't update

in JDK 1.1.4.  [Bug 4040388]

___________________
AWT KEYBOARD EVENTS - Caps lock and Shift keyboard events did not 
work properly on Win32 versions of JDK 1.1.3. This problem has been 
fixed in JDK 1.1.4. [Bug 4067542]

_________________________
AWT WINDOW ACTIVATION BUG - In JDK 1.1.3, invisible windows could not 
be activated, which caused applets to hang. This bug has been fixed 
in JDK 1.1.4.  [Bug 4068536]

_____________________
AWT COLOR SUPPORT BUG - Previous versions of JDK 1.1 did not correctly 
handle 8-bit TrueColor. This problem has been corrected in JDK 1.1.4.
[Bug 4061285]

_______
JNI BUG - In JDK 1.1.4, the JNI_GetDefaultJavaVMInitArgs function has 
been corrected to properly set the default system class path. In 
previous versions of the JDK, the default system class path was set to 
NULL.

________________
LOCALIZATION BUG - In the zh_TW.BIG5 locale, users could not input 
Chinese characters into the text area. This problem has been fixed 
in JDK 1.1.4.  [Bug 4053637]

____________________
java INTERPRETER BUG - In previous releases of JDK 1.1, the java 
interpreter would allow the class file at /a/b/c.class to be invoked 
from within the /a/b directory by the command "java c", even if the 
class c was in package a.b.*. This behavior is incorrect and has been 
fixed in JDK 1.1.4. In JDK 1.1.4, the fully qualified class name must 
be specified. For example, to invoke the class a.b.c at /a/b/c.class, 
the command "java a.b.c" could be issued from the parent directory of 
directory /a.

_________________
jdb DEBUGGER BUGS - Several Java debugger problems are fixed in JDK 
1.1.4. In previous JDKs, the debugger could not print a static member 
whose type was a string. Setting a breakpoint in a native method would 
cause the debugger to crash. These debugger problems have been fixed 
in JDK 1.1.4.  [Bugs 4064129, 4062582]

the Solaris JDK 1.1.2. The following list summarizes changes in 
JDK 1.1.3.
______________
VERSION NUMBER - The version number for this release is "JDK1.1.3".

________________
LOCALIZATION BUG - In Solaris versions of JDK 1.1.2, the mechanism 
for loading the ByteToCharConverter classes for non-8859_1 encodings 
was broken. Characters in text areas of windows did not display 
properly for non-English-language locales and non-Western European 
locales. This problem did not exist in JDK 1.1.1. This bug has been 
fixed in JDK 1.1.3.  [Bugs 4049223, 4055084]

___________________________
VERIFIER IMPLEMENTATION BUG - A bug in the JDK 1.1.2 verifier would

browser's address space. This bug is not known to be present in 
JDK 1.0.x. This bug has been fixed in JDK 1.1.3. [Bug 4059597]

______________ 
JAVA BEANS BUG - The method java.beans.BeanInfo.getMethodDescriptors() 
did not return MethodDescriptors for all externally visible methods 
in some situations. getMethodDescriptors() did not report methods 
having no arguments when those methods were defined later in a class 
than similarly named methods having arguments. This problem did not 
exist in JDK 1.1.1. This bug has been fixed in JDK 1.1.3. [Bug 4056837]

_______________
AWT REPAINT BUG - Synchronization problems with graphics in the 
Win32 version of JDK 1.1.2 would cause graphics deadlocks or 
crashes of the Java virtual machine in some situations. This problem 
did not exist in JDK 1.1.1. This bug has been fixed in JDK 1.1.3.
[Bugs 4049421, 4051303]

________________
java_g -prof BUG - The profiling option of the Java interpreter 
did not work in the Win32 version of JDK 1.1.2. Using a command

virtual machine to crash. This problem did not exist in JDK 1.1.1. 
This bug has been fixed in JDK 1.1.3. [Bug 4056944]

_______________________
AWT FONTMETRICS SPEEDUP - Improvements have been made to AWT font 
metrics in JDK 1.1.3, resulting in significant speedups for programs 
such as HotJava that rely heavily on text rendering. 
[Bug 4046795]

_________________
AWT COMPONENT BUG - In the Windows version of JDK 1.1.2, a race 
condition sometimes caused the HotJava browser to crash when disposing 
components that were in the process of being shown. This bug has 
been fixed in JDK 1.1.3.  [Bug 4051487]

________________
AWT GRAPHICS BUG - In the Windows version of JDK 1.1.2, multi-
threaded access to Graphics objects sometimes resulted in dangling 
pointers due to a race condition in awt_Graphics.cpp. This bug has 
been fixed in JDK 1.1.3. [Bug 4049421]

______________
VERSION NUMBER - The version number for this release is "JDK1.1.2".

____________
VERIFIER BUG - The JDK 1.1.1 bytecode verifier did not check to 
determine whether the number of arguments passed into a method is less 
than the amount of memory allocated to local variables for that 
method. There was no known security attack based on this bug. This bug 
has been corrected in JDK 1.1.2.

___________
SIGNING BUG - In JDK 1.1.1, digitally signed code could be 
manipulated to impersonate another digital signature from the list of 
signers that are recorded in the Java runtime. This bug has been 
fixed in JDK 1.1.2. [Bug 4048143]

_______
DSA BUG - In JDK 1.1.1, the same default seed was used for every 
invocation of DSA. This bug has been fixed in JDK 1.1.2. 
[Bug 4050406]

________________
AWT MENU BUG FIX - Trying to add a pull-right cascade menu to a 
PopupMenu in JDK 1.1.1 led to an exception. This problem did not

[Bug 4040638]

__________________
AWT DIALOG BUG FIX - Closing nested modal dialogs out of order would 
cause parent to remain disabled in some cases. This bug has been fixed 
in JDK1.1.2.  [Bug 4045610]

_________________
AWT FOCUS BUG FIX - Setting default focus caused applets to hang in 
some situations. This problem did not exist in JDK 1.1. This bug 
has been fixed in JDK 1.1.2.  [Bug 4038896]

____________________
APPLETVIEWER BUG FIX - Trying to save an applet from the Appletviewer 
led to an exception. This bug has been fixed in JDK 1.1.2.
[Bug 4036537]

________________
DEBUGGER BUG FIX - The debugger "dump" command converted double 
values to float values before displaying them. This bug has been fixed 
in JDK 1.1.2.  [Bug 4046775]

_______________
JAVADOC BUG FIX - The javadoc html output for interfaces repeated 
the word "interface" in the signature. This bug has been fixed in 
JDK 1.1.2.  [Bug 4041579]

__________________________
JNI INVOCATION API CHANGES - To better support the JRE, the 
Invocation API is extended in JDK 1.1.2 in a few minor ways. 
The changes do not break any existing code. The JNI Native 
Method Interface has not been changed. 

1. The reserved0 field in the JDK1_1InitArgs structure has been
renamed to "version." The JDK1_1InitArgs structure holds the
initialization arguments to JNI_CreateJavaVM. Callers of 
JNI_CreateJavaVM must set the version field to 0x00010001. 
JNI_GetDefaultJavaVMInitArgs has been changed to return a "jint" 
indicating whether the requested version is supported.

2. The reserved1 field in the JDK1_1InitArgs structure has been
renamed to "properties." This is a NULL-terminated array of 
strings. Each string has the format:

			name=value

indicating a system property. (This facility corresponds to the -D
option in the java command line.)
 
3. In JDK 1.1.1, the thread calling DestroyJavaVM must be the only
user thread in the VM. JDK 1.1.2 has lifted this restriction. If
DestroyJavaVM is called when there is more than one user thread,
the VM waits until the current thread is the only user thread, and
then tries to destroy itself.

_________________________
NEW jre COMMAND-LINE TOOL - The jre command-line tool is similar to 
the java command-line tool, but is intended primarily for end users 
who do not require the development-related options available with 
the java tool. For more information on the jre tool, see 
http://java.sun.com/products/jdk/1.1/docs/tooldocs/solaris/jre.html
or http://java.sun.com/products/jdk/1.1/docs/tooldocs/win32/jre.html. 
Source code for the jre tool can be found in the Windows JDK 1.1.2 
directory tree in the jdk1.1.2\demo\jre\win32 folder. In the 
Solaris JDK 1.1.2, jre source files can be found in the 
jdk1.1.2/demo/jre/solaris directory.


=======================================================================
Changes from JDK 1.1_Final to JDK 1.1.1
-----------------------------------------------------------------------

The following changes and bug fixes are in the JDK 1.1.1 final release.
This is a maintenance release.
______________
VERSION NUMBER - The version number for this release is "JDK1.1.1". 

_________
BUG FIXES - This version contains the bug fixes listed at the 
    web page mentioned above. 

____________
UTIL BUG FIX - Removed getMenu and getMenuBar methods from 
    util.ResourceBundle class. [Bug 4036076]

    This bug fix is mentioned here because it fixes an API bug
    in JDK 1.1.

    These two "convenience" methods were part of the beta release
    and were mistakenly left in the final JDK 1.1 after we
    discovered the design weakness they presented and decided to
    remove them.  It is a bug that they were included in the 1.1
    release, and you should not call these methods.   We have
