[vtkusers] JVM Crashes while Call vtkGlobalJavaHash.DeleteAll() in Ubuntu...

[Sebastien Jourdain]

Hi Sathish,

to free most of the memory you should remove the actor that you put
inside the renderer. By doing that you will allow the whole pipeline
to be released.
And if this is crashing on linux because no more actor are present in
the renderer, you can simply add a dummy text actor before removing
your actor.
