AMQ broker raises "Exception occurred processing: <Unknown> -> org.apache.activemq.transport.stomp.ProtocolException: The maximum data length was exceeded"

Solution Verified - Updated -

Issue

Why are we getting the following warning in the broker log when sending a Stomp message that is larger than wireFormat.maxDataLength (104857600 bytes by default)?

WARN ProtocolConverter - Exception occurred processing: <Unknown> -> org.apache.activemq.transport.stomp.ProtocolException: The maximum data length was exceeded

The exception is expected but why does it say <Unknown> in the error message?

Environment

  • JBoss A-MQ 6.2.1
