Conda installation: Unable to load native library

[stachlewski]

Trying to run the example from:
https://pyjnius.readthedocs.io/en/stable/packaging.html

The code runs correctly without pyinstaller.
With pyinstaller used (which otherwise works correctly), the resulting executable fails when run with:

Error occurred during initialization of VM Unable to load native library: �

(ASCII code 01 after the colon.)

Where do I go from here?

Env:
Windows Server 2019
Anaconda: Python 3.7.3, PyInstaller (conda-forge) 3.5, PyJnius (conda-forge) 1.2.0.
JAVA_HOME set to OpenJDK installed by conda <...>\Anaconda3\envs\fullconda\Library
PATH contains <...>\Anaconda3\envs\fullconda\Library\bin\server

I've tried doing the same with an installation of JDK8 and JDK11 along with a 64bit Python3.7.4, installing dependencies by pip.
The result is mostly the same. I managed to run the example after processing with pyinstaller only after removing jvm.dll from the dist directory. Yet a larger program still crashes with what looks like a buffer overflow.
