Summary0007674: [VTK Java] Crashes if setting null - Object
DescriptionFollowing code leads to a crash in jvm.dll:

vtkActor myActor = new vtkActor();
myActor.SetTexture(null);

Thus it is not possible to unset the texture of an actor. Same is true for all other functions with objects as parameter.

Additional InformationReason:
This is because JNI:GetObjectClass will be called with null object. This is not allowed (s.http://java.sun.com/j2se/1.5.0/docs/guide/jni/spec/functions.html#wp16334 [^]).

Fix suggestion:
In vtkJavaUtil.cxx change function vtkJavaGetPointerFromObject to:

JNIEXPORT void *vtkJavaGetPointerFromObject(JNIEnv *env, jobject obj)
{
    return obj == NULL ? NULL : (void*)(size_t)vtkJavaGetId(env, obj);
}

 IMHO this check could be moved into vtkJavaGetId to protect both methods
