two snapshots are from older builds, one is from 090908 which just shows a lot of native painting - closing please reopen if consistently reproducible in recent builds, thanks
I'm experiencing a similar issue: http://statistics.netbeans.org/analytics/exception.do?id=261391 Netbeans blocks frequently when working on a Facelets file, seemingly every time it reexamines the code for autocomplete or error checking. It is extremely irritating; the editor is practically useless. I am using latest nightly build (200909132344) with a fresh user folder.
Just for giggles, I tried renaming the file from a .xhtml to a .jspx. Same problem with deadlocking: http://statistics.netbeans.org/analytics/exception.do?id=261398 Looks like .txt works okay though.
Looks like csl/gsf hints wait for javac in awt. Marku, could you please have a look? Thanks.
Inside org.netbeans.modules.web.jsf.editor.hints.ElChecker.compute(), there is an unneccessary write lock on document, which result in above mentioned AWT freeze (see http://statistics.netbeans.org/analytics/exception.do?id=261391 from above). Please use read lock.
fixed in web-main#7ae412eebcd4, thanks for the analysis.
Integrated into 'main-golden', will be available in build *200909181401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/7ae412eebcd4 User: Marek Fukala <mfukala@netbeans.org> Log: #172057 - AWT thread blocked for 23711 ms.
