Exceptions from log files from red5 applications

[bigbluebutton-issue-import]

Originally reported on Google Code with ID 829

We run our demo server

   http://demo.bigbluebutton.org/

for many days without reboot.  Attached is a file containing the output of

  sudo bbb-conf --debug

which scans the logs files of potential errors.  This log files spans a few hours of
operation.

Some example errors from red5

/usr/share/red5/log/bigbluebutton.2011-01-21.log:2011-01-21 18:32:02,054 [RMI TCP Connection(79)-127.0.0.1]
ERROR o.a.c.loader.WebappClassLoader - A web application appears to have started a
thread named [pool-1-thread-2] but has failed to stop it. This is very likely to create
a memory leak.

/usr/share/red5/log/error.log:Caused by: java.lang.IndexOutOfBoundsException: Index:

This is a 'drive by' issue as I've not tried to duplicate these issues, but this is
a place holder for the moment to track these exceptions, duplicate them, and figure
out what's causing them.

This looks like the cause of http://code.google.com/p/bigbluebutton/issues/detail?id=1036

I'm guessing an undo is being performed and we get this exception so the whiteboard
is not properly cleaned up.
