[jira] Commented: (GERONIMO-4458) Another ClassLoader deadlock
during server startup
[ https://issues.apache.org/jira/browse/GERONIMO-4458?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12655293#action_12655293 ]
Kevan Miller commented on GERONIMO-4458:
----------------------------------------
So, looks like to me that our use of AspectJ is introducing cycles in ClassLoading -- creating the potential for this type of deadlock...
Will need to try and workout what ClassLoaders the AspectJ weaving is going to invoke. Don't know how we're going to fix, yet.
