Failed to create a JVM with the requested environment.

Dear all,

I have been working successfully with the package before but face problems when setting up PyImageJ on a different computer.

The problem already occurs in the initialization.

Here is a minimal script:

```
import imagej
ij = imagej.init(mode='interactive')
```

Error message:

> JVMNotFoundException Traceback (most recent call last)
> Cell In[1], line 4

I then tried to set the JAVA_HOME environment:

```
import imagej
import os
import imagej.doctor
imagej.doctor.debug_to_stderr()

os.environ["JAVA_HOME"] ="C:\Program Files\AdoptOpenJDK\jre-8.0.242.08-hotspot"
# ij = imagej.init('2.9.0')
ij = imagej.init(mode='interactive')

```
Then I get the following error message:

Please let me know what I am doing wrong.

Reproduce the minimal imagej.init(mode='interactive') call and inspect imagej/__init__.py around _create_jvm, then follow scyjava/_java.py and JPype's JVM finder. Check the debug output and Maven bootstrap failure on the reported Windows environment; done means the initialization path completes successfully with a supported JVM setup.
