Subject [jira] Commented: (JAMES-701) JMX HTTP adapter fails to start
Date Fri, 17 Nov 2006 17:23:39 GMT
    [ http://issues.apache.org/jira/browse/JAMES-701?page=comments#action_12450801 ] 
            
Bernd Fondermann commented on JAMES-701:
----------------------------------------

The problem described here is rather tricky and seems to be an Avalon/Phoenix issue.

For the time being I suggest as workarounds to use JDK 1.4.2 to be able to enjoy HTTPAdaptor,
or switch to another protocol if JDK 1.5 is needed.

I will continue trying to understand this. I can observe strange things when debugging Phoenix.

TBC...

> Without JMX enabled, James starts just fine.
> Copying the jars from the current MX4J release (3.0.1) into lib and bin/lib directories
does not help.
> Neither does configuring MX4J as the default MBean server via adding -Djavax.management.builder.initial=mx4j.server.MX4JMBeanServerBuilder
