Comment 5 Dusan Balek 2016-09-13 09:43:23 UTC 
PreferredCCParser should not call a tree's accept method passing a TreePathScanner without properly initialized parent path as an argument.
Comment 6 Martin Entlicher 2016-09-14 22:38:49 UTC 
This is a regression, unfortunately.
Can be reproduced by e.g. having an instance of an implementation of a Map in Variables window, for which the source class is not available.
Comment 7 Martin Entlicher 2016-09-14 22:41:42 UTC 
Fixed by changeset:   300732:a1107ac38927
http://hg.netbeans.org/core-main/rev/a1107ac38927

Please verify in trunk, will backport into 8.2 then.
Comment 8 Quality Engineering 2016-09-16 02:28:25 UTC 
Integrated into 'main-silver', will be available in build *201609160002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Comment 9 skygo 2016-09-16 16:10:33 UTC 
Hi, I check this with build linked by Jiri on the NetCAT list.

Was ok but I'm not sure I'm able to reproduce the exact context
Comment 10 Jiri Kovalsky 2016-09-16 16:25:45 UTC 
Thanks Eric. Integration approved. Martine, please merge the fix to release82 branch.
Comment 11 Martin Entlicher 2016-09-17 11:01:13 UTC
