Description Sven Gothel 2010-03-24 07:48:07 CET

---- Reported by kawin 2005-11-03 00:41:43 ----

The method com.sun.opengl.impl.GLImpl.checkBufferObject (in JSR-231 beta 1
release) generates 16 octets of garbage each time it is called. Since it is
likely to be called very often (thousands of times per frame) and since it is
very easy to reduce this garbage generation, it would be interesting to do so.

The proposed patch is to reuse a statically allocated int[1] instead of creating
one each time it is called. This won't cause any threading problem since the
method is already not thread-safe.

Fixed by adding a private instance variable per GL object.
