The biggest users of S3 space on embed other software within the gem.  Many of the embedded packages are jar files.  Having an alternate way of downloading the java packages will be an extreme help in reducing the size consumed by this tiny handful of gems.

Not every gem packages jar files, but it seems that gem authors need a way to ship third-party code their gems need to be useful for the users.  For jruby users the alternative is to embed all the jars needed which increases the costs on  We should find an alternative mechanism for other authors that create large gems.

In the mean time, I think we should remove the dependency name check from

We can possibly add it as a gem package time check to maintain most of the benefits.
