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

[Sebastien Jourdain]

Hi Sathish,

Did you try to call vtkGlobalJavaHash.GC() instead ? If you want to call
DeleteAll(), you really have to make sure that no VTK object is used inside
Java anymore. What I mean is, if for some reasons some methods get called on
the vtkPanel after calling deleteAll(), you are definitely in trouble.
