NullPointerException in MonitorChannelHandler #31
Description
Hello!
Saw an NPE once now during the summer from the plugin. Stack trace below.
openjdk8
centos7
dcache 2.15.10
Own compiled version of the monitoring plugin straight from git ( done at 2016-03-18 ( which is after last commit and the fix for #30 )) because we were seeing way way too many exceptions in the logs.
