IllegalArgumentException thrown in analysis of Java compiled with --add-exports

[mnd999]

Hopefully I'm in the right place. I've been looking at improving the Maven support in bloop for a project I'm working on. One of the Java modules in this project is hacking the module system using --add-exports which then seems to trip up in zinc when it tries the analysis step on the class that Javac spits out.

Essentially I'm getting this trace, which gets through javac with a warning because of the specific --add-exports jdk.javadoc/jdk.javadoc.internal.tool=ALL-UNNAMED passed in on the command line.

@mnd999 Were you able to find a fix for this..running across the same issue at runtime when adding a stored procedure jar to neo4j.

@bryan-atwood-kr Sorry, no this kind of internals is a bit beyond me. Bloop, I think is also using a zinc fork anyway so it might not even be their bug.
