If you configure the setup properly (namely creating the appropriate
properties in ${components.dir}/components.properties then this should
not be the case. IIRC you need to add a ecj.dir and setup that dir in
way we expect. Of course I am not sure any of this is documented ;)

 Classpath 0.93 does not compile with javac, nor does it compile with
jikes and thus has to use ecj. It will use any ecj as long as you have
configured it correctly.

Possibly. Are you volunteering to look into it? :)

That does not seem like desired behavior. Sounds like a bug either in
your java runtime or http proxy.

I have not tried it for a long time so I am not sure it still works ;)

As Ian indicated "ant real-clean" should do the trick.
