I had opened and closed an ant editor and clicked around in the outline. When I went back to the other ant editor I had open, clicking in the outline got: eclipse.buildId=I20100713-2016 java.fullversion=JRE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260sr8-20100401_55940 (JIT

Similar stack trace posted at bug 319297 though it's not clear if they're the same problem.
*** Bug 319297 has been marked as a duplicate of this bug. ***
1. Open your first Ant file. 2. Open the second Ant file. 3. Select something in the 'Outline' view. 4. Ctrl+W 5. Click something in the 'Outline' view. 6. The NPE occurs. 7. You also cannot close Eclipse now.
