Looks like the UnlinkObjects and _GetScreenImOn is already  executed under the same lock:
 - WComponentPeer.dispose->AwtObject::_Dispose()->Lock on SyncCS->WM_AWT_DISPOSEPDATA->awt_Component.cpp.dispose()->UnlinkObjects()
 - WWindowPeer.getScreenImOn()->SyncCall()->Lock on SyncCS->AwtWindow._GetScreenImOn()

I think the only thing you should do is to replace the usage of JNI_GET_PDATA by the JNI_CHECK_PEER_GOTO and add a label "ret" at the end so default value of "result" will be returned.
