# this explains the NullPointerException

# this looks suspect in the stacktrace
$Proxy10.service(Unknown Source)
Perhaps, look in the vicinity of lines in all those java files in the
stacktrace for the chance of a null object coming into play.

Since upgrading to 1.5.2 I've noticed a lot of exceptions that seem to
be related to the Apache proxy ajp connector:
