GraalVM provides tracing agent which allows to find JNI and Reflection classes used by an application and store them in configuration files. Using the tracing agent with UI application requires checking non obvious use cases to cover different application code paths: Drag & Drop, file choosers, input dialogs, key strokes, Look & Feels.
Key strokes provide the most vivid use case. AWTKeyStroke.getVKValue(String) method uses reflection to get a key code for for the requested
KeyEvent.VK_*string value. It requires pressing all keys used as key strokes in the application during the tracing agent usage.The proposed fix registers common classes used by AWT/Swing application on Linux System.
L&F UI classes are registered only for Basic and Metal L&Fs as UIManager.setLookAndFeel(String) method directly sets MetalLookAndFeel class. It is necessary to use the tracing agent when an application uses GTK, Nimbus, and other Look & Feels.
