It's a JVM issue, start the JVM with the parameter -Xrs to ignore this
Logoff event signal.

$ java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

$ java -X
<snip/>
    -Xrs              reduce use of OS signals by Java/VM (see documentation)
<snip/>
The -X options are non-standard and subject to change without notice.
