The following com.sun.tracing and sun.tracing classes should be changed to use sun.util.logging.PlatformLogger that deals with the case when the logging module doesn't exist:

com.sun.tracing.ProviderFactory -> java.util.logging.Logger (logging)
sun.tracing.MultiplexProviderFactory -> java.util.logging.Logger (logging)
sun.tracing.NullProviderFactory -> java.util.logging.Logger (logging)
sun.tracing.PrintStreamProviderFactory -> java.util.logging.Logger (logging)
sun.tracing.dtrace.DTraceProviderFactory -> java.util.logging.Logger (logging)
