Comment 2 Vladimir Kvashin 2015-09-25 20:36:57 UTC 
IDE log contains BadLocationException immediately before this NPE:


javax.swing.text.BadLocationException: Invalid (offset=2096 + length=39)=2135 > (docLen+1)=883
	at org.netbeans.modules.editor.lib2.document.EditorDocumentContent.checkBoundsInContent(EditorDocumentContent.java:310)

And code shows that if this BadLocationException occurs, then it is followed by the NPE this bug is about.

Well, this NPE is fixed by 
http://hg.netbeans.org/cnd-main/rev/f3cb56b4708b

As to the BadLocationException, I don't know how to reproduce it; anyhow this bug is about NPE, so I'm closing it as fixed.

Integrated into 'main-silver', will be available in build *201509261150* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
