Build: NetBeans IDE 7.3 (Build 201302132200)

OS: Windows 7

User Comments:
daveo17: Every time I pull a new version of a java system net bean's background scanning hangs at 99 or 100%.  Then it magically decides to finish. In the future, with no code changes, the background scans complete normally. No error are identified in the code.

I updated to JDK 1.7.2. I am using Windows 7 ultimate 64 bit with 8 gb ram.

I have exited and re-entered the IDE, rebooted my computer, and do not find a pattern.

I have waited hours for it to finish. This is wasting a lot of time. With the number of other reports of this error I am surprised at the lack of response to correct a serious issue.

eng.amrelbatal: when using from jsf core in any project,just restarting  netbeans it shows me scanning facelets libraries and it doesn't finish and stop all net beans functionality

Comment 2 Martin Fousek 2013-05-17 07:33:41 UTC 
Deployment descriptor FO refresh (which is unfortunately probably necessary after changes in DD version/type definitions) invokes refresh into the FaceletsLibrarySupport. And it is stuck there since in the meantime editor invoked getting facelets libraries which wasn't finished due to call back to the DD. I moved the FLS's invalidateLibrariesCache() into BG thread which should resolve this.

Fixed in web-main #7482eccf216c.
