Glimmer on JRuby 1.1.5

Glimmer is now compatible with JRuby 1.1.5.

Thanks to dacm for taking the effort to report a Glimmer incompatibility bug on Eclipse BugZilla:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=257793

It is now fixed.

Thanks to Steve, Tom, and Starling too for reporting that bug along with the fix.

The changes were deployed to both SVN and GitHub repositories.
