----------------------------------------
Summary: AMQP message read from page has wrong encode size
Key: ARTEMIS-2658
URL: https://issues.apache.org/jira/browse/ARTEMIS-2658
Project: ActiveMQ Artemis
Issue Type: Bug
Components: AMQP, Broker
Affects Versions: 2.11.0
Reporter: Francesco Nigro
https://issues.apache.org/jira/browse/ARTEMIS-2617 has introduced a change to
save AMQPMessagePersisterV2::decode from re-creating
AMQPMessage::extraProperties, but this has introduced a new way to adjust the
existing AMQPMessage::extraProperties's TypedProperties::size while decoding
the rest of the buffer.
In the original implementation, the existing AMQPMessage::extraProperties
created by AMQPMessagePersister::decode was completely overwritten.
Page::read can use an offset to search for a specific message in a page and
PageSubscriptionImpl is using PagedMessageImpl::getEncodeSize to compute this
offset: after a successfull Page::read, AMQPMessagePersisterV2::decode can
corrupt the extra properties encode size, making the next message unreachable.
This can be solved by preserving the original semantic ie overwriting the
existing AMQPMessage::extraProperties in order to fix the encode size.
