Attachment SourceForge Username: starksm. Description: A legible version of the deadlock traces. Filename: trace.txt. URL:https://sourceforge.net/tracker/download.php?group_id=22866&atid=376685&file_id=38843&aid=662098 > class loader deadlock new for 3.2Beta3 > -------------------------------------- > > Key: JBJMX-21 > URL: http://jira.jboss.com/jira/browse/JBJMX-21 > Project: JBoss JMX > Type: Bug > Reporter: SourceForge User > Assignee: Scott M Stark > > > SourceForge Submitter: dgantenbein . > Class loader deadlock occurs on Windows XP, > Windows 2000 and Linus. Using JDK 1.4.1_01 and > JBoss 3.2 Beta3. This was not a problem using JBoss > 3.2 Beta1. > For us, this deadlock occurs using Cactus' ant task to > do automated nightly testing (runservertasks). This ant > task starts JBoss, and JBoss freezes during startup at > various points. > At the bottom of this information is the information about > the deadlock from OptimizeIt's thread debugger. The > stacktraces to the two threads involved in the deadlock > are included (tcpConnection-8080-1 and main). For > tcpConnection-8080-1 thread, the resin classes appear > in the stacktrace. I have confirmed that the resin > classes shown in the stacktrace are NOT holding any > monitor on a class. > ------------------------------------------------------------ > Thread tcpConnection-8080-1 enters monitor > java.lang.Class 0xaf35760 first and then > org.jboss.mx.loading.UnifiedClassLoader3 0xb124f80 > while thread main enters in opposite order. > Thread [tcpConnection-8080-1] (Suspended)
