so with hotswaping you mean replacing a class at rutime in the VM
wihtout creating a new class... ok, once that is out, why did they say
it won't work for Groovy? Groovy creates classes too. I don't know how
that hotwaping is working and what restrictions it has, so I have no
idea what the problem could be. Afaik something needs to recognize that
we have a nes class file and that needs to be loaded in the VM that is
running in debugging mode. Since we produce oridinary class files there
are only two things that can be wrong... Either the class file version
is too low or the files are not recognized as changed. But I can only
guess. I have no documentation about hotswapping.

that might be, but does it place the class files where you need them?
Does intellij even consider that there is something from Groovy for
hotswapping?

and how do you compile the classes there? You use groovyc?

we can try to fix the issue, but we need more data on this
