The ManagedOperationDelegate class is found in jboss-profileservice.jar and so should not be required on the client side.

To reproduce this, the following client code can be used:
https://svn.jboss.org/repos/jopr/trunk/modules/tools/jbas5-plugin-descriptor-gen/

Just do:
mvn install
cd target
java -jar jopr-jbas5-plugin-descriptor-gen-2.3.0-SNAPSHOT.jar

Here's the stack trace:
