Perhaps some code would be in order? I can say from experience that
if you are manually deleting vtk objects in java, bad things will happen
because of the recent implementation of weak-references in the vtk JNI.
I have not had any experiences like yours, however, but I could look at
your code. What version of vtk?

a few messages about problems that occur when

<p>1. Set up a scene
<br>2. On every mouse click, change the color of an actor with
<br>actor.GetProperty().SetColor(...)
<br>3. Intermittently, actor.GetProperty() returns null (not limited to
<br>GetProperty(). In general, members of a class become null randomly).

occur in unix
<br> 2. This problem does not
occur in C++ with nearly identical code

<br>solutions or workarounds? Have you even run into this problem before?
It
<br>sounds like a garbage collection issue to me. Could it be a JNI issue
