Subject Re: OpenJDK 15 EA build 21 is now available

[sorry, I dropped ant-dev and Rory by accident]

Hi Deepak

in that case the best Ant can do is to fail with a useful warning
message as we do for the javah task on any JDK > 9 - and skip the tests,
obviously.

AFAIU there is no in-JDK alternative, which is different from javah
where we can point at javac -h.

The workaround we can suggest then will be to explicitly use the
excecutable attribute of the <rmic> task to point to rmic of a different
JDK. This should go into our next release, I guess.
