Hi,
Working on upgarding legacy application from ActiveMQ to RabbitMQ. Tech stack
consists of Spring (Spring OSGI migrated to Aries Blueprint as part of this
upgrade), CXF, Camel, RabbitMQ; integration of RabbitMQ with Camel via RabbitMQ
Component (http://camel.apache.org/rabbitmq.html), and few others, all embeded
in Equinox OSGi container, with Jetty.
We had this resolved for about two weeks then suddenly this stopped working -
i.e. deserialization of messages works with Strings / built-in types, however
utilizing custom types (our classes) fails with ClassNotFoundException at
`org.apache.camel.component.rabbitmq.RabbitMQMessageConverter.deserializeBody`.
Full stack attached.
Your help with clues/pointers as to why RabbitMQ would not be able to see these
classes - if bundles where they're contained export these packages as they were
previously when this worked - is much appreciated.
Kind regards,
Michal Siemaszko
