GCJ was always a prototype kind of.

Anyone serious would be paying for Excelsior JET, BEA JRockit, or the myriad of other commercial JDKs wihth AOT tooling.

In fact most likely one reasons why Excelsior is not more, is that now GraalVM and OpenJ9 exist as free bear.

PTC and Aicas still have it good, because few care about their embedded and real time customers.
