So I just fought the weirdest bug in a while: lately #Ghidra provides a #Python scripting interface based on #Jpype (PyGhidra).

I had this script where I thought I fixed a bug by referencing X.y.z instead of X.z. Except nothing changed, the buggy behavior is still there (the file output contains garbage).

I add logging, the logs appear and show everything is fine.

Add more logs, exceptions even (to stop at a specific state). They run and show all is fine.

After I restart Ghidra the bug is gone.

To be clear: there must be some kind of bytecode caching that affects my object reference but does not affect additional logging/exception throwing??

Any ideas?

Cheers people, anyone into C++ #CPP would like to help both the #Python and #Java communities at once?

I have this #jpype issue that affects many Portuguese-speaking users (and I bet, other international users) that have non-ascii chars in their folder names scattered through their OSs.... https://github.com/jpype-project/jpype/issues/1111

This causes trouble for me personally because #py5 depends on jpype and my students have #ThonnyIDE frequently in a directory with non-ascii chars in its path, due to their usernames or on "Área de Trabalho" (desktop)... etc.

I've been teaching #Processing for some time, now and again someone wants to work with #maps and #cartography and I revisit #unfoldingmaps http://unfoldingmaps.org/ (a #Java library) can anyone suggest something similar but for #Python?
(I could try using the #py5 #jpype Java bridge but I'd rather learn new Python libraries).
