Personally, I have the same problem of Py_Initialize() hanging indefinitely.
Here is the context in which it happens : I am developing an application in
Java, in which I use the library jep (https://github.com/ninia/jep), that
enables me to get a Python interpreter from Java, and I am developing and
testing it on Windows. My Python version is 3.8.2 and I am on Windows 10 -
version 1903.
When I test this library outside my app in a simple Java project, everything
works fine, and the interpreter works.
But when I try to use it in the app, it hangs indefinitely when I create the
interpreter. When I digged into the code of the library, I found out that it
occurs in the native code of jep, during the call to Py_Initialize(). I posted
an issue on the github of jep, and they brought me here. I bet this is related
to stdin and stdout when I see what dhamilton posted.
My Java's stdout is normal and writes in the console. I tried to reset or
redirect Java's stdin an stdout, but it doesn't change nothing.
And when I try to do this on Linux (my application is also on Linux), on Ubuntu
16, everything works fine and it doesn't hang indefinitely. So this only
happens on Windows.
About capturing a process dump, all I can get is a message displayed on the
Java console when I close the app (because it hangs indefinitely) :
# A fatal error has been detected by the Java Runtime Environment:
#
# EXCEPTION_ACCESS_VIOLATION (0xc005) at pc=0x302b9d8f, pid=11960,
tid=0x3f98
#
# JRE version: Java(TM) SE Runtime Environment (8.0_241-b07) (build
1.8.0_241-b07)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.241-b07 mixed mode
windows-amd64 compressed oops)
# Problematic frame:
# C 0x302b9d8f
#
# Failed to write core dump. Minidumps are not enabled by default on client
versions of Windows
# The crash happened outside the Java Virtual Machine in native code.
All of this is just my personal case, and it's probably not the same for
dhamilton. I hope it helped you.
