It was originally written for use in remote invocations, and thus doesn't lazy-serialize. When we started using it for caching, that IMHO was a mistake; we should have written a version that has the behavior discussed on this thread. anonymous wrote : Or any other JDK objects - Dates, etc. Just have to be careful to exclude anything that can wrap a non-JDK type. Also can't use instanceof in type checking. Re: "releaseObjectReferences(fqn)" as the method name, sounds good. The "flush" name was just me being lazy in my post. :) +1 as well to having this be the default behavior. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4115215#...
