I'm not a member of the project, but noticed the error description and perhaps 
can help.

The "java.lang.OutOfMemoryError: GC overhead limit exceeded" means that JVM 
Garbage Collector continuously tries to free more memory and eventually fails. 
This may be caused by a memory leak in the application. 

If that is the case, then I would suggest you to attach Plumbr (www.plumbr.eu) 
to your application and see if it pinpoints the source of the problem. If you 
get a report from Plumbr, you'll have the list of leaking objects and the line 
number of where objects are created.

The NPE exceptions are from webcam being used by another browser. This happens 
when a user joins BBB on a browser (e.g. Firefox), starts sharing cam, opens 
another browser (Safari), and starts the webcam. The webcam on the Safari 
browser will be blank because it's being used by Firefox.

This is fixed by work done by Felipe to check if webcam is available and if 
not, not to start streaming.

The GC overhead limit...is difficult to reproduce.

Using YourKit, we found that deskshare holds on to memory after the deskshare 
stream has stopped. After a while, this memory just increases. When there is a 
low available heap space, the GC will reclaim this memory but if there are a 
number of users, the GC can't reclaim memory quickly enough and eventually it 
will crash.

Setting the objects to NULL allows GC to reclaim memory earlier.

We'll keep this issue open to continue to test throughout the 0.8 testing cycle.

Made some changes to remove hanging objects.

Haven't seen on demo for a few weeks.
