java.lang.java.lang.NoClassDefFoundError

### The env
From a local installation ,run the code
```python
import imagej
ij = imagej.init('G:\\Fiji.app')

image_url = 'https://imagej.net/images/clown.jpg'
jimage = ij.io().open(image_url)

image = ij.py.from_java(jimage)

ij.py.show(image, cmap='gray')
```

### the result

```

```
So I don't have the ideal to fix it

Reproduce the example using imagej.init('G:\\Fiji.app'), then inspect imagej/__init__.py around init and _create_jvm, along with the scyjava and imglyb startup frames named in the traceback. Determine why the net.imglib2 class is unavailable; done means the example starts without the reported NoClassDefFoundError.
