Hello all;

This is a simple cleanup changeset that removes redundant initialization of fields to null from a number of collection classes. These field initializations may seem cheap but they do have a cost: - For volatile fields there is a measurable cost on some benchmarks for these extra initializations. - Larger byte code in methods. - For transient fields the initialization is misleading since it does not occur on deserialization. https://bugs.openjdk.java.net/browse/JDK-8035284 http://cr.openjdk.java.net/~mduigou/JDK-8035284/0/webrev/ Redundant null initializations in other components/packages will be handled in separate issues.
