    Description

      A spin off from JDK-8294278. The implementation of VarHandle::describeConstable for static fields uses VarHandles.getStaticFieldFromBaseAndOffset to map a base/offset/fieldType to a static Field. This assumes that the location of a static field returned by Unsafe.staticFieldBase is a Class object. It may need to be re-examined for this code to be usable with other VM implementations.
