Yeah but I would make sure that the issue is on my code an not something
intrinsic e.g. that jars are simply not supported.
So thanks for clarification and I can now better narrow down where
things are going wrong :-)

This should work for dev classpath loading. But I imagine you must be

an issue?

Just to give a more explicit example:
if i have
my.bundle=/tmp/test/target/classes,/tmp/test/target/test-classes,/tmp/testorg.junit-4.13.0.v20200204-1500.jar,/tmp/test/org.hamcrest.core-1.3.0.v20180420-1519.jar
should this work or do I need to explode the jar files into a folder?
