Hi Sergey,

The fix looks good. Just one question: in LWWindowPeer.destroyBuffers() you're removing a call to replaceSurfaceData(). Are you sure that this is OK?

-- best regards, Anthony

Hi Everyone, This is a fix for 4 memory leaks. 1. LWWindowPeer does not destroy backbuffer in disposeImpl(). 2. LWToolkit stores unused links to Peer. 3. Local references were not deleted in the AWTWindow.m, but according JNFJObjectWrapper.jObjectWithEnv documentation "returns a new local-ref, must be released with DeleteLocalRef". 4. OGLContext in some cases can cache CGLSurfaceData in this case our LWWindowPeer was not collected.
