Hi Miro,
there are new releases of upstream for python-jep, py4j and jpype. Unfortunately, me as
the maintainer of these packages did not find any time to update those. There's not
much sense actually to rebuild the outdated packages.

FTBFS of jep. There's some ongoing work to implement official support for Python 3.7:

FTBFS of jpype. Please be aware of PEP 432. No idea if upstream needs to provide a fix.
