[jira] [Created] (QPID-6798) Broker decompressing a message on
behalf of a client who cannot produces stack trace to Broker log
Keith Wall created QPID-6798:
--------------------------------
Summary: Broker decompressing a message on behalf of a client who cannot produces stack trace to Broker log
Key: QPID-6798
URL: https://issues.apache.org/jira/browse/QPID-6798
Project: Qpid
Issue Type: Bug
Components: Java Broker
Reporter: Keith Wall
Priority: Blocker
Fix For: qpid-java-6.0
Running the following, which has one client connection sending messages that are compressed on the client, and a second client receiving with compression turned off, forcing the broker to decompress the message on the client's behalf, produces the following stack trace in the Broker log.
I don't yet understand the issue - from the client's perspective the message appears to be received correctly.
