[BGPCEP-267] PCEP plugin is possibly not chaining transaction well enough

Blocks — Sun, 3 Mar 2019 11:50:29 +0000

Present in recent Lithium snapshot builds (PCEP features version 0.4.1-SNAPSHOT).

How to reproduce:
Start ODL, install medium amount of features, shutdown gracefully.
Start PCCs with small time between connect attempts.
Start ODL.

The error does not always happen; but when it does, karaf.log may look like this (the last warning is the bug):
