--------------------------------------
Summary: Failure to decode messages with both custom payload and
warnings in 3.x
Key: CASSJAVA-85
URL: https://issues.apache.org/jira/browse/CASSJAVA-85
Project: Apache Cassandra Java driver
Issue Type: Bug
Reporter: Tommy Stendahl
Assignee: Tommy Stendahl
We have reproduced the message decoding bug in java-driver 3.x. We found in
java-driver 4.x and reported it as CASSJAVA-70.
Its the same issue, custom payload is decoded before warnings but the protocol
specification have them on the opposite order.

The issue is in Message.java, Deconing warings are done on line 289-291, that
should be done before line 279.
