JDK-8056152 added a new constructor to java.lang.Thread to constructing Threads that do not
inherit inheritable thread-local initial values. All usages of sun.misc.ManagedLocalsThread in
the base module were also replaced with this new constructor. Given there is now a supported API
for creating such threads, other areas of the JDK should be updated to use it, where applicable. If all
usages are replaced, then sun.misc.ManagedLocalsThread can be removed.
