-
[~omkreddy] I'm happy to fix it, but Luke is already assigned. In any case,
sorry folks ☹. I took another look at my PR and since {{configurationKeys}} is
the only nullable field I don't think it's a systematic mistake.
One other thought: We could easily have the message generator add {{@Nullable}}
annotations to nullable fields to enable static checking for this kind of error.

Well, from the broker perspective, you are right. Only trunk is affected. What
I mean is we'll also hit NPE when using 2.6 clients talking to trunk broker.

[~ijuma] This should affect 2.6 as well since `configurationKeys` starts to be
initialized in 2.7, due to the refinement introduced by
[KAFKA-9432|https://issues.apache.org/jira/browse/KAFKA-9432]. Anyway, since
`configurationKeys` is a nullable, an empty check should be added when
processing the resources in AdminManager.

[~huxi_2b] I initially hit this when using the 2.5.0 cli (from the binary
distribution) against trunk (running in eclipse)
I was later able to reproduce using the cli built from trunk (./gradlew
assemble -PscalaVersion=2.12)
