Re: Run java test in IDE

Hi Jeff,

Thanks for the hint, indeed the initialize error is gone once I added the
`build/exposed` (the default path in which exposed .class files are dumped)
path to intellij as `resource`, now I got a different error but I think
it's somehow related to configuration of environment you mentioned above.

I am working on exposing the builtin modules in a similar way as the
builtin types, so that they can be proper modules in Python. Currently they
are 'type` and the module functions are reflected.

Cheers,
Isaiah
