-Xrs Reduces use of operating-system signals by the JVM, to implement shutdown hooks for abnormal JVM termination for

• CTRL_C_EVENT,
• CTRL_CLOSE_EVENT,
• CTRL_LOGOFF_EVENT, and
• CTRL_SHUTDOWN_EVENT.

If JVM running as a service CTRL_LOGOFF_EVENT should not initiate shutdown.
When the -Xrs option is used on Sun's JVM, the JVM does not install a console control handler, implying that it does not watch for or process CTRL_C_EVENT, CTRL_CLOSE_EVENT, CTRL_LOGOFF_EVENT, or CTRL_SHUTDOWN_EVENT.

Additiona consequences of -Xrs:

• Ctrl-Break thread dumps are not available.
• User code is responsible for causing shutdown hooks to run, for example by calling System.exit() when the JVM is to be terminated.
