[vtkusers] java memory

OK, I'm still getting a lot of JNI errors when I run the vtkGarbageCollector
that look like the following. Do you have any idea what's going on here?
Here is the code that it is being called from
private static class MyVTKClean implements Runnable {
private boolean runVTKDelete;
private int numDelete;
public MyVTKClean(boolean runVTKDelete) {
this.runVTKDelete = runVTKDelete;
}
public synchronized void run() {
if (runVTKDelete)
numDelete = vtkGlobalJavaHash.DeleteAll();
else
numDelete = vtkGlobalJavaHash.GC();
}
public int getNumDelete() {
return numDelete;
}
}
// I think the VTK clean up has to run
// on the EDT, so we'll do that here
public synchronized static void cleanSystem(boolean runVTKDelete) {
System.gc();
System.runFinalization();
MyVTKClean run = new MyVTKClean(runVTKDelete);
// I'm not sure what to do here, it crashes sometimes
// I honestly think we're going to have to go through the program
// and just manually manage all our own memory.
SwingUtilities.invokeLater(run);
}
Here is a reproduction of the JNI VTK error.
