      Description

        We need to sprinkle volatile (or in future find some better way of doing lazy-init) over some fields in core reflection that appear to be accessed via a data race. This adds to the sprinkling of "final" in the same classes in JDK-8062771 and coordinates with related fixes to jdk7u and jdk8u
