I would like to add one point: GCJ can be used to cleanly bootstrap the OpenJDK from source with a chain that starts with GCC’s C compiler, to GCJ, to OpenJDK 6 (via IcedTea).
(The only wart is that later versions of GCJ rely on a pre-built jar of
ecj.)
This is why the bootstrappable builds project lists “Maintaining the GNU Compiler for Java” as a collaboration project.[1]
