Hi

What do you mean by "a crash due to messaging a dead object"?
Comment 2 Sven Gothel 2012-03-18 16:08:53 CET 
Dank you David, looks interesting, ie. not taking care of the 'NEWT' lifecycle when 'pulling the Applet'.

Will look at it later ..

Fixed w/ JOGL commit 4e0eb391d6c64f956ea5c87c0385ab48a24b2175
