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.

Made some changes to remove hanging objects.
Haven't seen on demo for a few weeks.
