de.flapdoodle.embed.mongo: MongodExecutable.stop() never ends on Windows

Hi,

We have a working unit test on Linux that didn’t work on Windows.

We’re starting a database at the begining of the test then stopping it at the end via the MongodExecutable.stop() method. On Windows, the test never ends and get killed by surefire after the timeout.

When killing, surefire takes a thread dump and here what we see:

Killing self fork JVM. Received SHUTDOWN command from Maven shutdown hook.

I’m also seeing this (or a similar issue) with tests passing on mac os and hanging on windows.

OpenJDK Runtime Environment (build 17.0.2+8-86) Windows 11 de.flapdoodle.embed:de.flapdoodle.embed.mongo:2.2.0

The test fails to complete with:
