__PYVENV_LAUNCHER__ set to MacPorts python causes TypeError

[rhoerbe]

Launching a UnitTest from within PyCharm 5 with a virtualenv causes "TypeError: Can't mix strings and bytes in path components" on executing "from jnius import autoclass". This happens in a path operation joining $JAVA_HOME with jre/lib/server/libjvm.dylib. This is looking like a follow-up error, but hardly traceable in a standard python debug environment.

This behavior occurs with MacPorts python 3.4. I am just documenting this; possibly the error handling could be improved?

The error message came up in various conditions. Using the scenario above but with python 3.5 resulted in the same message, regardless of the setting of PYVENV_LAUNCHER

8 years later, is this still repeatable?
