RE: Fwd: gcj can not import packages

From the link, it looks like it would be correct to say that gcj is the *on=
ly* open source way to bootstrap OpenJDK.

I would like to add one point: GCJ can be used to cleanly bootstrap the Ope=
nJDK from source with a chain that starts with GCC=E2=80=99s 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 =E2=80=9CMaintaining th=
e GNU Compiler for Java=E2=80=9D as a collaboration project.[1]
