Comment by Periyasamy Palanisamy [ 19/Dec/16 ]

This is not reproducible with normal ELAN use cases.
It looks like NullPointerException is thrown only after EtreeInterface augmentation.
I suggest Alon's team to look at it.

Comment by Alon Kochba [ 19/Dec/16 ]

Peri, why do you correlate this to ETree usage?
This was found in CSIT - meaning it probably reproduces using the standard operations used in CSIT - none of these include Etree as far as I know..

Comment by Periyasamy Palanisamy [ 20/Dec/16 ]

Yes Alon, Looks like it occurs due to faster add/remove of elan interface from CSIT test cases. Assiging to myself to look further.

Comment by Periyasamy Palanisamy [ 02/Jan/17 ]

Its fixed in https://git.opendaylight.org/gerrit/#/c/49635/.
