I had the same issue with the Java IdentityHashMap bug. I wanted to replace a Mina class that used IdentityHashMap with a temporary custom implementation that used HashMap instead, put it on the classpath ahead of mina.
Simple solution was to put my custom class in the project itself, in this case under src/unittests. When maven invokes tests it puts target/classes and target/test-classes on the classpath ahead of other dependencies. Maybe this is not quite so usefull to you? I was able to do this because I only needed the replacement for testing against in-vm brokers and not for anything else. Perhaps you could put your extra class in qpid-incubating.jar, which gets loaded first and holds the classpath for the remaining jars? At least, the conventional start up scripts would pick it up first. On 22/11/2007, Martin Ritchie <[EMAIL PROTECTED]> wrote: > > Maven experts.
