Confluence makes Tomcat/JVM to crash

Problem:
JVM crashes sometimes for unknown reasons.
If we try restarting the Tomcat it doesn't restart.
When we did a comparison of running copy with backed up one we found following files corrupted.

! D:\temp\confluence-1.2_OLD\confluence\WEB-INF\lib\batik\batik-1.1.1.jar: CRC failed in org\apache\batik\parser\ClockParser.class. The file is corrupt

! D:\temp\confluence-1.2_OLD\confluence\WEB-INF\lib\ehcache-0.9\ehcache-0.9.jar: CRC failed in net\sf\ehcache\constructs\blocking\BlockingCacheManager.class. The file is corrupt

! D:\temp\confluence-1.2_OLD\confluence\WEB-INF\lib\lucene\lucene-1.4-final.jar: The archive is corrupt

! D:\temp\confluence-1.2_OLD\confluence\WEB-INF\lib\XMLParser\xmlParserAPIs-2.2.1.jar: Unknown method in org\w3c\dom\html\HTMLSelectElement.class
