Release 1.8.0 - 05/05/2006</h2></div></div></div><div class="abstract"><p class="title"><b>Abstract</b></p><p>Release 1.8.0 adds a number of minor improvements and fixes. Most notably, checkpointing can now be achieved with a single command (with the requisite pause/resume done automatically), and all URIs fetched may be tagged with the original seed URI from which they were discovered. (This source URI information is both in the crawl.log and a new 'source-report.txt' report available among the disk file reports.)</p><p>We expect release 1.8.0 to be the last release officially supported on JDK 1.4.x ("Java 2") Java; future releases will require JDK 1.5.x ("Java 5") Java facilities.</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="1_8_0_limitations"></a>3.1.

Workaround is to locate the 'state' directory on a non-NFS-mounted volume. </p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="bdb_jdk16"></a>3.1.2. "Channel closed, may be due to thread interrupt"</h4></div></div></div><p>An error with this message has been observed intermittently when running on the Sun Java 6 ("mustang") beta JVM ("-beta2-b81"). A forthcoming fix from Sleepycat for BDB-JE may be necessary to resolve this issue. </p></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="1_8_0_changes"></a>3.2.

Progress Statistics Log</h4></div></div></div><p>The format of progress statistics' state-change log messages have been modified. State-change messages now have a tail that adds some context explaining why we're pausing, etc. Note, we will be adding originator of the status-change event to the progress statistics log post 1.8.0 -- i.e. whether event came of JMX or via the UI -- so be prepared for more progress log changes.</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="checkpointing"></a>3.2.2. Checkpoints</h4></div></div></div><p>Now when you ask to checkpoint a running crawl, it will manage for you the pause, checkpoint, and resume cycle (If paused when checkpoint is invoked, the crawler will be set back into a paused state upon checkpoint completion). </p><p>Checkpoints made with 1.6.0 software cannot be recovered with 1.8.0 software. Core classes such as CrawlController have changed so their serialized representation as part of a checkpoint has also changed (We have not done the work to deserialize earlier versions of core classes serialized as part of a checkpoint).</p></div><p><div class="table"><a name="N105B8"></a><p class="title"><b>Table 3.
