Kernel dies when using #! syntax on Windows

[imagejan]

On Windows, it seems that any use of the shebang (#!) syntax to select the language leads to a blocked kernel.
When run with jupyter notebook, there's an error message that the kernel died. When running with jupyter lab, the kernel stay in "restarting" state forever (i.e. it seemed to work fine at start, and gets restarted as soon as you run a cell with #!python, #!groovy or some such).

(tested with version 0.3.0-0 from conda-forge)

I was using System.getProperty("line.separator") to detect the first line with the shebang but it appears that Jupyter notebook returns string with \n for new line (this is why it works on Linux).

That should fix it : a09ee52

@imagejan would you mind testing it? Just replace your current kernel jar file by this one: https://drive.google.com/open?id=0Bwt2y0cMI-oyYjZPUEJOUlA2blU

You'll find the file under PATH_TO_CONDA/envs/java/opt/scijava-jupyter-kernel (work on Linux, OSX and Windows).

Once you confirm me it's working. I'll release a new version.

[imagejan]

👍 Great! I just tested 0.3.1-SNAPSHOT and confirm that it's working now.

[hadim]

Awesome. I'll release 0.3.1 today.

Linux and OSX package for 0.3.1 are available on conda forge. (Windows should follow soon).
