Please use the opportunity to think a bit about whether there are any holes in JRMP as well. That code's been looked over a lot more, so less likely to have issues, but another quick review can't hurt. anonymous wrote : I will probably create a different jira for this, rather than using JBAS-4950, because this jira focuses on the calling invocationHasReachedAServer() upon successfull returns, rather than exception handling itself. Thoughts? Yes, this is a separate issue. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4103665#...
