ConcurrentModificationException in Processing

[yireh]

Hello! I had problems running the MotionCapture3D example while running it on Processing 1.2.1
I get "ConcurrentModificationException" error message while running the following line:
for (Skeleton s: skels.values())

anyone has a solution? This problem happens when there are more than one users

Seems i forgot to protect data structures for multi-thread access. I'll patch it up soon.

this seems to be still there.
What I experience is it happens only when in multiusers you have let's say user 1 then user 2
then you loose user 1
then again user 1 gets in and it catch the exception

It's not happening if you have let's say user 1 then user 2
then you loose user 2
then again user 2 gets in
