No, I didn't come around to test it yet. Sorry. I will try to do it this week.

> Currently, required user JAR files are distributed via the RPC service in 
> {{JobGraph.writeRequiredJarFiles(DataOutput, AbstractJobVertex[])}}. The RPC 
> service then tries to allocate a buffer on the client side heap to write the 
> on-disk JAR, which [can lead to 
> problems|https://github.com/apache/incubator-flink/pull/18].
> This should be replaced with a seperate service.
