UI is unable to display consumer groups for a topic

[katheris]

Issue Description

The IBM Event Streams UI is unable to display consumer groups for a particular topic and
the log output for the Admin REST component shows an exception similar to the following:

java.lang.IllegalArgumentException: Invalid negative offset

See Kafka issue 9507{:target="_blank"}.

When processing a list offsets request the Kafka Admin Client does not filter out offsets with value -1 and gets an IllegalArgumentException when it creates the response.

Environment

• IBM Event Streams Version: 2019.4.3, 2019.4.4

Issue reference: ES-139
