[Maxim Areshkau (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-4839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12483938#action_12483938 ] 

Maxim Areshkau commented on JBIDE-4839:
---------------------------------------

Why TaglibMapping.revalidate is synchronized?
And why is it method called using Display.syncExec()? see https://jira.jboss.org/jira/secure/attachment/12327657/ThradWhichBlocksMaiinThread.txt file from JBIDE-4534. If this revalidates taglibs, it's can be done in non ui thread.
