Description Filip Brychta 2017-02-10 15:02:12 UTC 
Created attachment 1249053 [details]
storage node screenshot

Description of problem:
See attached storageNode.png, the exception is very probably thrown because the Heap Used metric has NaN value because it's not enabled by default.

Version-Release number of selected component (if applicable):
JON3.3.8

How reproducible:
Always

Steps to Reproduce:
1. install JON 3.3.8
2. navigate to Administration->Storage Nodes->Your storage node
3. Heap Used metric should be NaN because it's not enabled by default

Actual results:
globally uncaught exception

Expected results:
No exception because of NaN

Additional info:
See bz1138328, they didn't find a root cause but it very probably the NaN values.

I've already reproduced this issue disabling the Heap usage metric manually, also I sent a PR for fix this.
