I improved synchronization in trunk:
http://hg.netbeans.org/web-main/rev/ea3ece30d92c

I need crash report to verify, that above commit is the fix.

crash report
Comment 8 Jan Becicka 2013-09-25 08:01:49 UTC 
John, both crash reports are not related to this bug, but to bug 236338.

Please send me all those reports, I'll grep them.

zip crashes.zip ~/Library/Logs/DiagnosticReports/java*

and attach crashes.zip to this issue or send the directly to me.
Thanks

Well my crash was different, not related to iPad (as I don't have an iPad). I started seeing regular crashes after updating to JDK 7u40, and I already reported those as bug 235863.
Comment 10 Marian Mirilovic 2013-09-25 15:03:00 UTC 
As QE is not able to reproduce and verified reliably in 7.4, we will not fix it in 7.4 . Leave it as candidate for future possible patches.

Comment 12 Jan Becicka 2013-09-25 18:38:14 UTC 
There are 13 Java crashes in John's logs. 11 of them are related to issue 236338.
One is related to this issue. We are not able to reproduce this crash. Let's close this issue as fixed by ea3ece30d92c and let's reopen it, if anyone is able to reproduce it even with ea3ece30d92c.
Comment 13 Petr Jiricka 2013-09-25 22:21:46 UTC 
Good, thanks. But I still don't understand why not put this patch into 7.4, if John confirms that it fixes the problem on his side. After all, crash is a P1, no?

I doubt, that John can reliably reproduce it. If he (or anyone else) can reproduce it and verify the fix I'm also for integration. But AFAIK we cannot reproduce it.
Comment 15 Vladimir Riha 2013-11-12 12:32:42 UTC 
I've tried running HTML5 project on iPad, some debugging and web inspection and it work so this fix/improvement doesn't seem to cause some regression but I cannot reliable verify it.

As far as I know, there wasn't any similar report from users since 7.4 was released. Do we still want to put it into patch?
