It's a bit shamy closure-compiler does not work on JRuby (due to fork).

Now the #10 is not the right way as the compiler Java code does a System.exit once done and thus it'll exit the current JVM process which is not desired.

If the popen is replaced with a Tempfile that is passed as a --js argument while invoking the compiler using "`" it works nicely on JRuby as well as Ruby + no Windows hustle necessary.


The patch looks good -- can you make sure that it unlinks (deletes) the tempfile after it's done with it?

That should to it, thanks for the review.

+1 for merge. Need JRuby support.
