EDT is blocked for 41s (plus ten before profiling started) in org.openide.text.CloneableEditorSupport.closeDocument()

Comment 3 Jaroslav Tulach 2013-07-22 10:01:18 UTC

Very likely the closeDocument waits on 

org.openide.text.CloneableEditorSupport.prepareDocument()	99.92449	41 709 ms (99,9%)	0,000 ms

which is blocked 

org.netbeans.modules.cnd.source.CppEditorSupport.createStyledDocument()	99.92449	41 709 ms (99,9%)	0,000 ms

The original intention of the API was expecting createStyledDocument method to be fast. If it takes 51s then it is sort of violating the API contract. Passing to CND team.

Comment 4 Andrew Krasny 2013-07-22 15:02:29 UTC

Jarda, you are right and the described flow is correct but only for a single report 681682 (out of 29).
Other reports have nothing to do with cnd. Only this (681682) log file shows up loaded cnd modules.

So I'm going to file another separate issue against cnd and re-assign this one to platform.

Comment 5 Andrew Krasny 2013-07-22 15:07:39 UTC

A bug for cnd-related report (http://statistics.netbeans.org/exceptions/exception.do?id=681682): https://netbeans.org/bugzilla/show_bug.cgi?id=233191

Comment 6 Andrew Krasny 2013-07-22 15:08:58 UTC

I'm not sure if 'platform' is the correct category. Please adjust appropriately. 
Thanks!

Wulpo@netbeans.org, don't change metadata of issue, we do need to know in which version it was reported initially

Comment 8 Andre_Lopes_2012 2013-07-30 15:55:44 UTC

I reported it in Netbeans 7.4 :P 
I always use last ( beta ) versions. 

It lags when i try to refactor!!
