I encountered this as well and it appears to be a mylyn or SWT bug.

Mylyn handles opening attachments.

Comment 2 Kevin Sawicki

Do you still get this exception if you disable the mylyn reviews plug-ins?

Comment 3 Christian Trutz

2011-04-18 16:47:03 EDT

I cannot reproduce the NPE ...

Comment 4 Chris Aniszczyk

2011-04-20 11:24:17 EDT

I get this also and have Mylyn Reviews installed (Gerrit integration).

Comment 5 Kevin Sawicki

2011-04-20 11:27:40 EDT

I think it comes from the line in CommentAnnotationRulerColumn.createControl
where fViewer.showAnnotations(true) is invoked.

Comment 6 Chris Aniszczyk

2011-04-20 11:29:47 EDT

I sent an email to mylyn-reviews-dev for some info.

Comment 7 Chris Aniszczyk

2011-04-20 11:47:37 EDT

moving to Mylyn Reviews

Thanks for investigating that Kevin. I have pushed a fix and triggered a new build: https://hudson.eclipse.org/hudson/job/mylyn-release/97/.

Sorry, make that https://hudson.eclipse.org/hudson/job/mylyn-release/99/.
