I believe so - on Linux. Windows-specific changes are mostly covered (I verified `Java_java_awt_Component_initIDs()` (from `awt_Component.cpp`) and `D3DRQ_FlushBuffer()` (from `D3DRenderQueue.cpp`). Not all the `AwtDesktopProperties::Set...Property()` (from awt_DesktopProperties.cpp ) are touched by the test. I originally applied the changes to all the similar code there without verifying that each piece is invoked by the test.
