I was a bit puzzled by this because line 119 in DiagStatusServiceMBeanImpl has no Optional.get(), until I remember that jluhrsen was working on INFRAUTILS-31 and looking at https://git.opendaylight.org/gerrit/#/c/70220/4/diagstatus/impl/src/main/java/org/opendaylight/infrautils/diagstatus/internal/DiagStatusServiceMBeanImpl.java saw that his added this there:

.append(status.getErrorCause().get())

which is causing this. So this is a mistake on that change, which is not present. I'll therefore put a review comment on that change and close this issue.

Staring at this code, and this comment from jluhrsen, has however prompted me to question something in that code:

Something might be wrong in my environment that is blocking localhost/127.0.0.1
from working here?

and I'll follow-up on that in INFRAUTILS-37.

Comment by Jamo Luhrsen [ 02/May/18 ]

I updated INFRAUTILS-38 and 37 with what I learned, and now back to this as it's still a problem to figure out.

I tried to see if I could replicate the problem with a unit test and I thought I was close with this but I realize
that the new UT code was still failing with or without the .get(), so I doubt it now.

Anyway, I can help/debug, but I think I'm limited with what I can do on my own from there. Looking for
guidance.
