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]
