The source is available somewhere, I have seen it.

java@gcc.gnu.org is the best place to ask java questions.  Let's see 
what they say over there.

sourceware.org:/pub/java holds both ecj-4.3 and ecj-4.5

That site holds the binaries of both ecj-4.3 and ecj-4.5.  It has the
source code only for ecj-4.3. What I am interested in is the *source
code* for ecj-4.5.

OK, I found the source repositories by looking at the ecj-4.3 source.
ecj is in CVS at sources.redhat.com:/cvs/rhug, and its Makefile
obtains the upstream compiler source from Eclipse CVS at
:pserver:anonymous@dev.eclipse.org:/cvsroot/eclipse.

What is still not clear is: what version of the ecj CVS project
corresponds to "ecj 4.5"? It doesn't look like there are branches or
tags in the CVS repository.

Is there any way to know who put the ecj-4.5 binary jar file on
sourceware.org? Perhaps we could ask that person to put the
corresponding ecj source tarball on the FTP site as well?

Also -- the ECJ source contains a single Java file (for the class
org.eclipse.jdt.internal.compiler.batch.GCCMain), in addition to
downloading the rest of the compiler source from eclipse.org. GCCMain
doesn't have any license statement in its header, and there is no
license in the ECJ source repository at sources.redhat.com. What
license applies to o.e.j.i.c.b.GCCMain? Is it under the EPL, or the
GPL, or something else?

Cheers!

Yeah, oops.  We've been remiss in doing that.

I believe 4.5 was made from CVS head.  IIRC, Matthias made it and I
uploaded it.  So maybe he knows for sure.  We can make a tag once we
know for sure.

I think it has to be EPL.  It was derived substantially from the Eclipse
compiler driver.
