Thanks, I solved it by letting the program be aware of what windows are still active. If all windows are killed then all opengl "pointers" are cleared from java-side shared state. When creating a new window I check if there are any alive and reference that context as a sharewith. Little bit of extra bookkeeping but worth it for the performance gains :).
