Description Marco Descher CLA 2012-12-03 03:13:05 EST 
I created a sample application for an article to come up accessible on https://github.com/col-panic/central-icon-management

The code works flawlessly on Eclipse 4.2 SR1 with Java 7. Using the newest integration build (I20121127-0800), however, the code fails with the enclosed exception.

I can mitigate the NPE by adding if (tableViewer !=null) before the tableViewer, but the program still does not work correct. To visualize the problem take a look at the enclosed screenshots showing the good (4.2) and the bad (4.3) version of the program.

I could als re-enact the problem on Windows XP.

Already documented in https://bugs.eclipse.org/bugs/show_bug.cgi?id=394327 and discussed in http://www.eclipse.org/forums/index.php/m/986775/ 

Proposed fix adding @Inject works, sorry for bothering.

Adding @inject will workaround this bug, but it will break your application again when the bug is fixed.

The bug should be fixed in I20121127-0800 if this is not the case then please reopen bug 394327
