I did not restart when prompted to install Windows Builder, since there was an option to 'Apply Changes' accepting the risk that there might be errors.  

If there are errors that inhibit functionality they should be removed from the options available, in my opinion.
Windows Builder information at http://www.eclipse.org/windowbuilder/support.php.

Reproducible: Didn't try

Moving to WindowBuilder as this does not demonstrate a bug in PDE. I suspect that this is caused by using the apply changes option.  The extension point framework does not handle changes at runtime and needs to restart.  However, the install is handled by p2 which has no way of knowing whether the units it installed require a restart or not.  Note that some plug-ins may function fine without restart depending on what extension points they use.
Comment 3 Eric Clayberg CLA 2011-09-20 10:45:40 EDT 
This is a well known Eclipse issue that has nothing to do with WindowBuilder.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=228247

Bottom line: never use "Apply Changes". Always restart after installing anything significant.
