deeplearning4j: Java 10 problem with UIServer due to Play

Got bitten by something like this today - this issue discusses the problem: https://github.com/jhalterman/typetools/issues/34

It looked like this for me:

@saudet, I was able to launch org.deeplearning4j.examples.convolution.Cifar example with override under Java 11, but I did not test override with entire library. Let’s review and merge this: https://github.com/deeplearning4j/dl4j-examples/pull/785, then I will switch to override.
