Picking not working when using GLJPanel

Hi!

I use JOGL to draw some meshes and I use the basic OpenGL picking (with the select buffer, etc...). When I use a GLCanvas, it works fine. When I use the same code with a GLJPanel, if the picking returns at least one hit, the application freezes a few seconds later. Has someone already had the same problem?

I get this kind of exception when resizing the Eclipse ViewPart:
