Thanks
I see that EVERY ThreadLocal now has an extra field in case it is
used with a Supplier. I expect that those web frameworks that create
thousands of ThreadLocals (not just instances of Threadlocals)
will see a measurable space increase. has anyone measure the impact?
Did anyone consider instead defining a SuppliedThreadLocal
subclass (or some better name) to isolate the impact?
