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

Logfiles showing that Resin successfully is starting up:

Now, I killed it with

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

(0003513) stbu 10-19-08 07:46	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.
