most of this is ranting, and marketing.
please ask azul to post jtreg test results (and/or compare these for yourself)
and find out that the Debian packages are on par or better than the azul
packages. Debian doesn't have access to the TCK, and Debian shouldn't go into
any defensive mode to compare to any non-publically available test suite.
