We started noticing this recently, but not sure if it's always been there or not. Now we are
starting to mark test case failures if exceptions are seen. We can whitelist these, but my
gut is that this is something new. Or if not new, I think it's showing up a lot more now.

an example
{code{2018-04-17T21:53:26,448 | ERROR | Karaf ssh console user karaf | ShellUtil | 135 - org.apache.karaf.shell.core - 4.1.5 | Exception caught while executing command
java.lang.NullPointerException: null

like from a job here where it's seen 21 times.

I realize the trace is pointing to something in karaf, so odlparent seemed like the right
place to open this issue.
