Comment 5 Tomas Hurka 2016-10-31 14:47:17 UTC 
This looks like deadlock in editor.
Comment 6 Jiri Kovalsky 2016-10-31 14:59:38 UTC 
Cezariusz, is there a chance for you to share with us the project privately or at least its structure? Ideally a sample project with the same setup reproducing the problem. Thanks!

I have created a new project group, opened the project causing the dead lock and it worked properly, so it's not related to that particular project. Actually it's a very simple ANT project with only one class file. So the problem might be related to the project group, with consist of many project of various types including Java Ant, Java Maven, NetBeans Module, NetBeans Suite, Web Ant, and C/C++. It's close to impossible to share all project from that group.

Previously I've been using the debugger on that project and I've pinned some variables. It might be related if pinned variables are stored somewhere in the project group.
