yes, it really sounds like I looked into another webrev...

Here are some comments from my side:

1. On X11, we don't have any other toolkits than XToolkit, so I don't 
see any point in checking the AWT_TOOLKIT var on X11.

2. On Mac, CToolkit is not explicitly set in awt_LoadLibrary.c - I 
realize it's used by default (inherited from java_props_md.c), but it 
would be fine to leave a comment in the code.

3. AFAIK, there is no need to check global refs for NULL: 
DeleteGlobalRef() is ready to handle null refs.
