Created attachment 123619 [details] stacktrace Product Version = NetBeans IDE Dev (Build 20120827-a1447f4e3665) Operating System = Linux version 3.2.0-27-generic running on amd64 Java; VM; Vendor = 1.7.0_06; Java HotSpot(TM) 64-Bit Server VM 23.2-b09; When I was editing .jsp file my IDE got frozen due to attached deadlock. Feel free to reassign I took a look on that really shortly. BTW, I don't have exact steps to reproduce. :/ I just used CTRL+TAB to switch to NetBeans and then move my mouse cursor over something.
Probably related to my recent change in threading of selectElementNode - I will take a look.

Integrated into 'main-golden', will be available in build *201209050001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-golden/rev/806bf2a79d3a User: Jan Lahoda <jlahoda@netbeans.org> Log: #217472: everything related to CSL navigator must run on background, apparently.
I hope the above will be sufficient.
