[jira] [Created] (CASSANDRA-14087) NPE when CAS encounters empty
frozen collection
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:
