Yes, but it errors out (so it doesn't start). I get this:

start.human.task:

t set, defaulting to build.sysclasspath=last; set to false for repeatable builds

Now it apparently doesn't like the Java +minor+ version I'm using. I really don't want to have to regress to Java 1.5 if I don't have to. Why is jBPM so picky about the Java version numbers? Aren't they all backwards compatible? What's the +latest+ version I can get away with? Thanks again!
