and to be clear, according to the source file header, the JSR166 version
is "Adapted and released, under explicit permission, from JDK

I don't know what explicit permissions were given to the JSR166 group
for their use of that code, so it may be just fine for us to use anyway
in this context.  That said, given that we received the contribution of
an ALv2 equivalent, we considered it prudent to use that instead.
