-----------------------------------------
Summary: CBUtil serialization of UTF8 does not handle all UTF8
properly
Key: CASSANDRA-20234
URL: https://issues.apache.org/jira/browse/CASSANDRA-20234
Project: Apache Cassandra
Issue Type: Bug
Components: Messaging/Client
Reporter: David Capwell
Assignee: David Capwell
The following error was presented to the user from java driver
{code}
Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 512 out of bounds
for length 6
at
com.datastax.driver.core.Responses$Result$Kind.fromId(Responses.java:339)

com.datastax.driver.core.Responses$Result$1.decode(Responses.java:306)
at
com.datastax.driver.core.Responses$Result$1.decode(Responses.java:303)
{code}
The issue is that there is an off-by-1 issue with track warnings serialization
where the estimated size and the actual size don’t match, which cause the
client to read result kind of 512 (which isn’t valid)
