Comment 2 Alexander Simon 2016-07-11 11:16:12 UTC 
I believe that NPE is consequence of:
INFO [org.netbeans.spi.lexer.MutableTextInput]: !!WARNING!! Missing READ-LOCK when accessing TokenHierarchy: input-source:org.netbeans.modules.editor.NbEditorDocument@2b26d83a, mimeType='text/x-c++', kitClass=null, length=97, version=10, file=org.netbeans.modules.cnd.source.CCDataObject@3ca2471d[/export/files/NB/CppApplication_1/main.cpp@da0e3936:4e7ece75]
It should be fixed in the bug 262248.
