[jbosstools-issues] [JBoss JIRA] (JBIDE-18878) Eclipse livelock(?) at startup with hibernate builder in stacktrace

[Snjezana Peco (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-18878?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13026378#comment-13026378 ] 

Snjezana Peco commented on JBIDE-18878:
---------------------------------------

I have faced the issue many times before. In my opinion, it isn't related either to hibernate or to Equinox.
The issue is related to initializing the WorkbenchThemeManager class because it uses Display.syncExec.
When starting, the org.eclipse.ui.editors plugin requires the WorkbenchThemeManager class, which sometimes causes Eclipse to lock.
I haven't found a reproducible case, but when the issue happens, I have to remove the workspace.

In this case (based on https://issues.jboss.org/secure/attachment/12386721/12386721_jstack-output.txt) the org.eclipse.ui.editors and org.eclipse.ui.navigator lock to each other.
We would, probably, have to create a new upstream issue.
