Subject Re: [jira] Commented: (AMQ-1383) org.apache.activemq.transport.InactivityMonitor$1 cannot be cast to edu.emory.mathcs.backport.java.util.concurrent.Delayed
Date Mon, 15 Oct 2007 11:32:45 GMT

Hi,
I have pretty the same error with ActiveMQ 4.1.0, JDK 1.5.0, WinXP SP2.
The only difference seems to be in the error msg:
