Summary

0016122: Fix for freeze with Java JOGL interaction

Description

I seem to have found a solution to the problem with JOGL referenced in this conversation:
http://www.vtk.org/pipermail/vtkusers/2014-May/084032.html [^]

To recap, the following doesn't work and freezes on Windows:
- Screen capture (Using VTK code)
- Rubber band type of interaction where a rectangle get drawn on top of
window.
- Volume rendering

Upon starting a rubber band interaction, vtk goes into an infinite loop in GetPixelData when clearing the OpenGL errors. This, I think, is a red herring. Basically, OpenGL gets into a bad state somehow.

The fix seems to be to force the context to be current in the java code. In vtkAbstractJoglComponent.java, the fix is to not check if the context is current, but instead always make it current (i.e., the if statement is commented out, forcing the makeCurrent() statement):

                // Make sure the JOGL Context is current
                GLContext ctx = drawable.getContext();
                //if (!ctx.isCurrent()) {
                    ctx.makeCurrent();
                //}

I've only tested this on Windows using a vtkInteractorStyleRubberBandZoom with VTK 6.1 and 7.0. It likely fixes the other issues and platforms, but someone else will need to test those.
