org.netbeans.modules.extbrowser.SimpleExtBrowserImpl.setURL(): 15361 / 0 - running external process in AWT
Comment 4 Tomas Mysik 2012-11-08 13:08:28 UTC 
Davide, is this yours? If not, please reassign back to me, I can have a look at it.

Thanks.
Comment 5 David Konecny 2012-11-08 23:35:50 UTC 
No, sorry, not mine. P4 IMO - problem has always been here I think.
Comment 6 Tomas Mysik 2013-07-17 07:05:11 UTC 
The fix could be to run ExtBrowserImpl.loadURLInBrowser(URL) always in a background thread - Davide, do you see any problem with it? Don't you know, please? The only problem I can see is that setting "url" field would usually happen before the url is actually loaded in the browser, see [1] (now, it is synchronous) - no idea whether it would be OK or not.

Thanks.
[1] ExtBrowserImpl.setURL(URL)
Comment 7 David Konecny 2013-07-23 03:22:28 UTC 
I would wait and see if we get more reports like this one. HonzaB change code in WebBrowserPane.showURL recently to allow to be called from a background thread.
Comment 8 Tomas Mysik 2013-07-23 07:11:52 UTC 
OK, no problem with that.

Honzo, please have a look at comment c#6 - if you think it is safe to do that, let me know. Otherwise we will wait for more reports as David suggests.

Thanks.
Comment 9 Jan Becicka 2013-07-23 11:41:55 UTC 
It should be OK for external browsers. Im not sure about embedded WebKit
Comment 10 Tomas Mysik 2013-07-23 12:10:35 UTC 
OK, let's wait for another reports and fix it in the next release.

Thanks.
Comment 11 Tomas Mysik 2013-10-08 09:03:13 UTC 
One more report from 7.4 RC2, so fixed as written in comment #6. Láďo, please verify.

Thanks.

I tried to open various browsers on Mac and no problem. I will do the same later on Windows and Ubuntu
