Hide
Cause:
Large messages sent when the broker is configured with zero persistence (by setting persistence-enabled in broker.xml to false) are lost while logging an IndexOutOfBoundsException warning
Consequence:
Larges messages cannot be used if the broker has disabled persistence
Fix:
Large messages are now encoded correctly by a broker with disabled persistence
Result:
Larges messages can be handled by a broker with no persistence

Change the minLargeMessageSize where needed (on the locator, the connection factory or as an URL parameter as suggested here https://activemq.apache.org/artemis/docs/1.5.5/large-messages.html) with a value >= 138249 (or the maximum large message size in bytes + 88 bytes) avoiding the message to became a large message (with null storage) and being wrongly encoded.
