[ http://jira.jboss.com/jira/browse/JBAS-4441?page=comments#action_12363187 ] Adrian Brock commented on JBAS-4441: ------------------------------------ This issue is caused by JBAS-4066. The classloader in 4.2.x now catches java.lang.LinkageError and assumes it is a spurious ClassCircularityError caused by the JDK bug. The problem is that with this broken configuration, the LinkageError is real. There should be a maximum number of retries and then it should give up, e.g. 10 attempts? There is a numCCE in the ClassLoadingTask but this is not currently maintained or used. The suggested patch in LoadMgr3 would be something like: catch(Throwable e) { boolean retry = e instanceof ClassCircularityError || e.getClass().equals(LinkageError.class); - if( retry) + if( retry && loadTask.numCCE < 10) { + ++loadTask.numCEE; /* Reschedule this task after all existing tasks to allow the current load tasks which are conflicting to complete. */ etc. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
