Tyler Hobbs created CASSANDRA-7440:
--------------------------------------
Summary: Unrecognized opcode or flag causes
ArrayIndexOutOfBoundsException
Key: CASSANDRA-7440
URL: https://issues.apache.org/jira/browse/CASSANDRA-7440
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Tyler Hobbs
Assignee: Tyler Hobbs
Priority: Minor
Fix For: 2.0.9, 2.1 rc2
If an unrecognized opcode or flag is used in a native protocol message, it
results in an unhandled ArrayIndexOutOfBoundsException server-side. This can
happen when features from a new protocol version are used with an older
protocol version.
Here's one example stacktrace:
