<< Synopsis >>
Memory consumption increases when I set a texutre object on two or
more view objects over and over.
<< Description of the Problem >>
Texture mapping problem.
I attempt to set a texutre object on view objects(sphere, box, and so
on) with following conditions.
・ texture object is refleshed in succession.
・ two view objects share only one texture object.
Finaly, "OutOfMemoryError" occurs.
I consider that texture memory is not freed.
I could not find out the problem with following conditions.
・ texture object is refleshed in succession.
・ a view object is textured a texture object.
・ another view object is textured a texture object is made from
"Texture#cloneNodeComponent()" method.
I consider that two view objects should be able to share one texture
object.
<< example program >>
create a texture object from "1.jpg" file when a mouse click on the
frame.
And two sphere objects are textured the texture object.

I recognized it via "window NT task manager".
And see "process tab" - "image name" - "java.exe".
thank you.
