This was a bug introduced here:
2016-06-26 Per Bothner <per@bothner.com>
* MakeScene.scm (MakeScene): Don't create Group until actually needed.
I checked in a fix, in both the master and kawa-2.4 branches.

I was able to reproduce it before, though only on the old 2.4 branch.
It seems to have gone away - though it might be JDK or other environment issues.
Let me know if you still experience it with the kawa-2.4 branch.
Of course, you could also switch to the master (formerly 'invoke') branch;
I doubt I'll make another 2.4.x release.
