Yes, I've made the 4.5.1 task use a classloader to avoid creating a new VM.
It was a little involved but the same strategy should work for the 5.1 task.
I'm looking into it.

No, I prefer a resource. The loading of the resource is based on the
classpath, so I don't need to know the actual file location. It does mean
that you need to have your weblogic classpath set up before you run ant. I
don't really like that - I try to run a mimimal classpath. Nevertheless, it
works for now.

These changes should be good. I'll look into them.
