Yes.   This is a known problem.   There's not a simple work-around,  
unfortunately.   The problem is that the replay system does not have a  
way of dealing with custom class loaders, which eclipse uses  
extensively.   This problem has existed from the beginning---it's an  
artifact of the design of the replay compilation implementation.  I've  
gone and created JIRA for it:  http://jira.codehaus.org/browse/RVM-825
