Bryan Pendleton commented on DERBY-5851:
----------------------------------------

I tried running 'ant -verbose' to see if I could better understand how the 
emma-single
target works. I've pasted the output of the instrumented JUnit invocation below.

It's interesting, to me, that we appear to have *both* sets of Derby classes in 
the
classpath: the instrumented derbyrun.jar comes first, and then my normal sane 
jars
come afterward (although derbyTesting.jar comes before the instrumented 
derbyrun.jar)

Is this how it is supposed to look? Or should I *only* have the instrumented 
derbyrun.jar
in my path?
