Subject [jira] [Updated] (CAMEL-7586) NotCompliantMBeanException : Attribute MessageHistory has more than one getter
Date Tue, 08 Jul 2014 15:38:04 GMT

     [ https://issues.apache.org/jira/browse/CAMEL-7586?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Lefillastre Alexandre updated CAMEL-7586:
-----------------------------------------

    Description: 
Hello, I wasn't able to subscribe on the mailing list, so I'm posting my issue directly here.

In my project I need to use some ManagedCamelContextMBean, which I am trying to access through
: [JMX.newMBeanProxy|http://docs.oracle.com/javase/8/docs/api/javax/management/JMX.html#newMBeanProxy-javax.management.MBeanServerConnection-javax.management.ObjectName-java.lang.Class-]

However, it is not working as I'm getting a NotCompliantMBeanException as the attribute MessageHistory
seems to have more than one getter.

I checked the source code of newMBeanProxy, then the JMX 1.4 specification ( http://docs.oracle.com/javase/8/docs/technotes/guides/jmx/JMX_1_4_specification.pdf
), and then Camel's source code, and it appears that ManagedCamelContextMBean is indeed not
respecting the standard MBean.

The problem is that two methods are defined in ManagedCamelContextMBean : isMessageHistory()
and getMessageHistory()
Since the return type is boolean, isMessageHistory is considered to be a getter, which makes
two getter according to the JMX specification and is blocking the newMBeanProxy() method.
