[jira] Updated: (HARMONY-6123) [classlib][awt] locking assertion
failure in X11 library
[ https://issues.apache.org/jira/browse/HARMONY-6123?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mark Hindess updated HARMONY-6123:
----------------------------------
Attachment: xnextevent.locking.diff
This patch adds calls to XLockDisplay/XUnlockDisplay around a single call (XNextEvent) that appeared in the backtrace for this bug. Sadly it deadlocks if attempted with one thread waiting with the (new) lock in XNextEvent and another presumably trying to obtain a lock in XSendEvent. Will discuss this further on the dev@ list.
