JOGL incompatible with SWT 4.21

Hi Martin,

Thanks a lot for your comments and fixes !

I thing this hack/fix works extremely reliably in an OSGI environment, where the behaviour of the class loader is completely deterministic, especially regarding the order in which it looks at classes. In other setups, I cant be so sure ... We will continue to use this, anyway, in GAMA, which is using an OSGI architecture.

Cheers
Alexis

Dear Peter,

thank you - I merged your patch.

I updated the SWTAccessor and build system for SWT 4.26, all pushed to git.

So far, it seems to work (SWT headless and w/ AWT).
While working on the 2.4.0 release, I will check test results in more detail.
