Summary 0003009: NullPointerException when Resin-3.1.7a is killed using ./httpd.sh kill
Description [2008/10/19 15:59:16.059] WatchdogProcess[Watchdog[],1] stopping Resin
Exception in thread "watchdog-" java.lang.NullPointerException
        at com.caucho.boot.WatchdogTask.run(WatchdogTask.java:112)
        at java.lang.Thread.run(Thread.java:619)



Steps to reproduce:


Resin was started with

stbu@linuxhost:~/resin-pro-3.1.7a$ bin/httpd.sh start
Resin/3.1.7a started -server '' for watchdog at 127.0.0.1:6600

 Just to make it clear:
Normally Resin is stopped with './httpd.sh stop' and that works as expected without a NPE.
Just in case one would kill Resin with './httpd.sh kill' a NPE should be avoided when possible.
