problem with Rex::Lang::Java meta.yml

[paulo-graca]

When trying to install Java module using rexify:

rexify --use=Rex::Lang::Java

I'm getting an error message:

Getting dependencies for Rex::Lang::Java...
JSON text must be an object or array (but found number, string, true, false or null, use allow_nonref to allow this) at /usr/bin/rexify line 361.

I think the problem is related with the Rex::Lang::Java meta.yml file and the empty list of dependencies.
