-----------------------------------
Summary: browseMessages() fails when using Jolokia to browse JMX
Key: AMQ-4177
URL: https://issues.apache.org/jira/browse/AMQ-4177
Project: ActiveMQ
Issue Type: Improvement
Environment: 5.7.0
Reporter: james strachan
Priority: Minor
I tried using Jolokia to browse the JSON view of JMX for ActiveMQ. Things
generally worked great, however the browseMessages() function causes issues
with the Jolokia JSON marshaller - it seems we return beans which are not
really usable as is. Not sure how easy this is to fix...
Here's the stack trace when browsing a queue called 'cheese' on a JVM running
ActiveMQ and jolokia servlet such as with a URL like:
http://localhost:8080/jolokia/exec/org.apache.activemq:BrokerName=localhost,Destination=cheese,Type=Queue/browseMessages()
{code}
{
error_type: "java.lang.IllegalStateException",
