I think this is not a JOGL bug. It is more related to GTK. You can set the environment variable as described in my previous link.

Here is described how you start an application inside of Eclipse with a variable:

(see the post from aspiring_sarge)

For me only xim worked but it is said it should'nt be used (see previous post)

In the shell something like "export GTK_IM_MODULE=ibus" should work.
