> Key: CASSANDRA-21738
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21738
> Project: Apache Cassandra
> Issue Type: Bug
> Components: CQL/Semantics
> Reporter: Nadav Har'El
> Priority: Normal
> Fix For: 5.0.x, 6.x, 7.x
>
>
> When a prepared statement's {{USING TIMESTAMP ?}} bind marker is given an
> empty (zero-length) value, the request fails with a server error caused by a
> NullPointerException:
> {code:sql}
> CREATE TABLE ks.t (k int PRIMARY KEY, v int);
> -- prepare, and bind ? to an empty (0-byte) value:
> INSERT INTO ks.t (k, v) VALUES (1, 1) USING TIMESTAMP ?;
> {code}
> {noformat}
> Server error: java.lang.NullPointerException: Cannot invoke
> "java.lang.Long.longValue()" because the return value of ... is null
> {noformat}
> Reproduced on Cassandra 5.0.9 and 6.0-alpha2.
> CASSANDRA-17822 fixed the same NPE for {{USING TTL ?}}:
> {{Attributes.getTimeToLive()}} now treats an empty value like null, i.e. no
> TTL ({{InsertTest.testEmptyTTL}}). But {{Attributes.getTimestamp()}} has no
> such check. It validates the empty buffer, and
> {{LongType.instance.compose()}} returns null for it, which is then unboxed
> into a long.
> Expected: an InvalidRequestException, like the one for a null value ("Invalid
> null value of timestamp"), instead of a server error.
