Description

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.

skitt vorburger any ideas on this bug? It adds 40-50 exceptions to the karaf.log so looks messy.

Comment by Robert Varga [ 23/Apr/18 ]

The log is located at https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/netvirt-csit-1node-openstack-queens-upstream-stateful-oxygen/465/odl_1/odl1_karaf.log.gz

The stack trace is:

2018-04-17T20:20:15,270 | ERROR | Karaf ssh console user karaf | ShellUtil                        | 135 - org.apache.karaf.shell.core - 4.1.5 | Exception caught while executing command

Requires karaf-4.1.6

Thanks rovarga. good to know the fix is there and we'll get it eventually.

Comment by Sam Hague [ 24/Apr/18 ]

Is there a plan to bring in karaf-4-1.6? Or can we pull in that patch since it is just a 3 line patch.

Comment by Stephen Kitt [ 24/Apr/18 ]

Once it’s released, maybe, but it won’t be released for a little while yet. It’s just a 3 line patch but releasing a new bundle with that code and getting it loaded isn’t straightforward!

Comment by Robert Varga [ 24/Apr/18 ]

FWIW 4.1.6 is scheduled for release on 5/18.

Comment by Robert Varga [ 05/Sep/18 ]

Fixed with karaf-4.1.6 (odlparent-3.1.4) and karaf-4.2.1 (odlparent-4.0.0)
