Subject [jira] Commented: (DERBY-3406) IllegalMonitorStateException in ...replication.master.AsynchronousLogShipper.workToDo(:320)
Date Tue, 12 Feb 2008 16:45:08 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12568204#action_12568204
] 

Knut Anders Hatlen commented on DERBY-3406:
-------------------------------------------

AsynchronousLogShipper.workToDo() calls notify() without synchronization, which is not allowed.
