Hi!!!
Is there any documentation or place where I can find description of
classloader hierarchy in merlin? Maybe it will help me solve this issue.
Thanks,
Jarek

I got very strange results :(
I removed mrt-service-impl.jar from block.xml classpath, I got
com.mrt.AbstractService NotClassDefFoundException, which is ok.
I put mrt-service-impl.jar again on block classpath and added cglib.jar to
CLASSPATH variable,net.sf.cglib.reflect class was loaded successfully but
then I got following exception
which is very strange for me because com.mrt.BussinessServiceException class
is placed in mrt-service-impl.jar from which com.mrt.AbstractService was
successfully loaded.

Merlin has found the class but the class cannot be properly constructed.
This is typically because the class is referencing another class that
is unknown with the classloader hierarchy. My guess is the the cglib is
doing something that requires classes in the system classloader. A
solution to this problem may be to move the cglib jar file from the
block definition to the classpath used to run the unit test. But this
itself could be problematic as ant creates its own classloader above the
system classloader.
What happens when you run the block directly using merlin from the
command line?
