Description

Synchronization problems revealed a synchronization issues in libclient_java that heavily impacted synchronization (see #7631)

mostly we want to remove the synchronized keywords from two methods in RestClient to allow the static RestClient used by default by D1Client impls to process more than one request in parallel.

We also need to adjust the singleton instantiation mechanism of the D1Client classes. (http://stackoverflow.com/questions/7048198/thread-safe-singletons-in-java)
