Jason Brown commented on CASSANDRA-13734:
-----------------------------------------
I have a petty fix to stop the {{BufferUnderflowException}}, but I'm not sure
it addresses the root of the problem with the buffer (if indeed there is a
problem with the buffer). Further, it doesn't explain the reported problem wrt
uppercase UUIDs, but we need more information to see how it's related to the
reported exception.
Performing a non-JSON read seems to work perfectly fine for [~clauds2x], so
that we can assume is working correctly. To at least alleviate the JSON
problems we can change [this line line in
{{Selection}}|https://github.com/apache/cassandra/blob/cassandra-2.2/src/java/org/apache/cassandra/cql3/selection/Selection.java#L380]
from this:
{code}
if (buffer == null)
sb.append("null");
{code}
to this:
{code}
if (buffer == null || buffer.remaining() == 0)
sb.append("null");
{code}

> BufferUnderflowException when using uppercase UUID
> --------------------------------------------------
>
> Key: CASSANDRA-13734
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13734
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra 2.2.8 running on OSX 10.12.5
> * org.apache.cassandra:cassandra-all:jar:2.2.8
> * com.datastax.cassandra:cassandra-driver-core:jar:3.0.0

> We have a table with a primary key of type uuid which we query for results in
> JSON format. When I accidentally caused a query passing a UUID which has an
> uppercase letter I noticed that this causes a BufferUnderflowException on
> Cassandra.
> I directly attempted the queries using cqlsh, I can retrieve the entry using
> standard select but whenever I pass JSON I get a BufferUnderflowException.
