Description
The broker currently uses the sun.misc.Signal(Handler) classes directly within the ServerConfiguration class, creating both a reliance on the classes existing (they are far more prevalent than just the Sun JDK as might be expected, but their existance isn't guaranteed) and also causing unsuppressable compiler warnigns during the build.
The use of these classes should be isolated from ServerConfiguration to allow use of the broker on JDKs which do not support them, and additionally their use should be proxied using reflection to remove the associated compiler warnings.
