Subject [jira] [Created] (CASSANDRA-14087) NPE when CAS encounters empty frozen collection
Date Fri, 01 Dec 2017 11:19:00 GMT
Jens Bannmann created CASSANDRA-14087:
-----------------------------------------

             Summary: NPE when CAS encounters empty frozen collection
                 Key: CASSANDRA-14087
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14087
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jens Bannmann


When a compare-and-set operation specifying an equality criterion with a non-{{null}} value
encounters an empty collection ({{null}} cell), the server throws a {{NullPointerException}}
and the query fails.

This does not happen for non-frozen collections.

There's a self-contained test case at [github|https://github.com/incub8/cassandra-npe-in-cas].

The stack trace for 3.11.0 is:
