RFR raw types lint warnings fixes for java.util.concurrent

[Joe Darcy]

Hello concurrency maestros,

I submit for your consideration a simple patch to silence the three 
remaining javac lint warnings in the java.util.concurrent package:

I am content to relinquish ownership in seeing this patch through the 
166 -> JDK 8 integration process :-)
