JDK LogManager and shutdown hook in Sun's JRE

Sun's LogManager has an undocumented feature where System.exit()
invokes reset() on the LogManager.

This causes problems for other Shutdown hooks like JBoss's that stops all services.
i.e. the loggers can be reset while another shutdown hook still wants to use them

A potential fix is to set the system property to install our own LogManager that
disables reset. Instead we do the reset processing from
our own shutdown hook.

// psuedo code
public class JBossLogManager extends LogManager
{
protected JBossLogManager()
{
}

public void reset()

{ // do nothing }

public void jbossReset()

{ super.reset(); }

}
