Is there some reproducible scenario, or some sample code available? Thanks.

ErrorDescriptionFactory.createErrorDescription should not be called with null position. Honzo, could you please have a look at it? (Analyzer:createSignaturePositions ?)

It appears that TreeUtilities.findNameSpan(Tree) returns null positions. Unfortunately I cannot do more without further
info. I have added logging to Analyzer that should shed light on what's wrong.

arittner: your broken source file seems to have invalid positions for AST.

Fixed as http://hg.netbeans.org/main/rev/7301cc555180. The issue should not occur any more.

Integrated into 'main-golden', will be available in build *200809100201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Log: #134663: even more defensive fix for broken source codes

> arittner: your broken source file seems to have invalid positions for AST.

Yes, it's an c&p:

Clipboard:

private boolean x = true;

and paste in:

public Ctor () {
  |
}

Thank you for your fast fix. I'll test it asap.
