I can build on jdk8 and seem to be able to start {{./bin/cassandra}} after
switching back to jdk7, but with the changes from CASSANDRA-14821, I don't
understand how we can verify testing on jdk7 and jdk8, as this branch has
always done, if build.xml now specifies we must use jdk8 in tests.

I'm unclear as to why such a breaking chnage was committed to the 2.2 branch -
can we revert CASSANDRA-14821 [~ifesdjeen] to rework dual-JDK support for this
branch or just leave it out entirely, going back to the previous working tests?

Can you add the exact steps to reproduce this? {{Consumer}} is available
starting Java 8 and looks like your issue is in 2.2 backport.
