Issue running the %%java prefixed cells in ambit

[oolonek]

Hi,

I wanted to give a try to the https://github.com/ideaconsult/notebooks-ambit/blob/master/structure_standardization/ambit_standardize_demo.ipynb notebook.

However when I run the first cell in a notebook running on the Python kernel I get a
UsageError: Cell magic %%java not found.

I am not familiar whith running java inside Jupyter notebooks. I installed beakerx (https://github.com/twosigma/beakerx) and launched a jupyter-lab instance after selecting java11 as kernel.
The returned error is then :

py4j.Py4JException: An exception was raised by the Python Proxy. Return Message: Traceback (most recent call last):

RuntimeError: There is no current event loop in thread 'Thread-4'.

Also I could not run the first cell using the binder instance.
I guess I am missing an obvious instruction here ...

Happy to have your help here !
Thanks
