Description Jiri Skrivanek 2006-06-27 08:41:08 UTC 
A random dead lock appeared when I call "CVS|Merge Changes from Branch" action.
There were opened several enterprise and web projects and breakpoints were set
in several files. But I can't reproduce it anymore. I guess something wrong is
either in JspToggleBreakpointActionProvider

org.netbeans.modules.web.debug.actions.JspToggleBreakpointActionProvider.propertyChange(JspToggleBreakpointActionProvider.java:65)

or in JEEVerificationAnnotationProvider

org.netbeans.modules.j2ee.verification.JEEVerificationAnnotationProvider.processDocument(JEEVerificationAnnotationProvider.java:191)

Please, look at attached thread dump and fix it if it is possible or re-assign.

"Java EE Verification Request Processor" thread begins MDR transaction
(JEEVerificationAnnotationProvider.processDocument()), then in
FolderList.waitProcessingFinished() waits for the "Folder Recognizer" thread to
finish but this thread in turn tries to enter MDR transaction again which IMHO
causes the described deadlock.
Reassigning to java module to evaluate because it tries to start the transaction
in the listener code.

btw, JspToggleBreakpointActionProvider listens on the node selection change and
retrieves the web module for it. AWT thread is blocked waiting for the "Folder
Recognizer" thread (now IDE is frozen). But is has nothing to do with the deadlock.
