<DD>Returns a LocalVariablesInfo object containing information
 about the usage of the local variables in the Code attribute
 of the said method or <B>null</B> if the class file this
 Pass2Verifier operates on could not be pass-2-verified correctly.
 The method number method_nr is the method you get using
 <B>Repository.lookupClass(myOwner.getClassname()).getMethods()[method_nr];</B>.
 You should not add own information. Leave that to JustIce.<DD><DL>

<DL>
<DD>Pass 2 is the pass where static properties of the
 class file are checked without looking into "Code"
 arrays of methods.
 This verification pass is usually invoked when
 a class is resolved; and it may be possible that
 this verification pass has to load in other classes
 such as superclasses or implemented interfaces.
 Therefore, Pass 1 is run on them.<BR>
 Note that most referenced classes are <B>not</B> loaded
 in for verification or for an existance check by this
 pass; only the syntactical correctness of their names
 and descriptors (a.k.a. signatures) is checked.<BR>
 Very few checks that conceptually belong here
 are delayed until pass 3a in JustIce. JustIce does
 not only check for syntactical correctness but also
 for semantical sanity - therefore it needs access to
 the "Code" array of methods in a few cases. Please
 see the pass 3a documentation, too.<DD><DL>
