What am I doing wrong? hg: lambda/lambda/langtools: More bug fixes:

[Howard Lovatt]

Hi Maurizio,

Latest push in Mercurial repository has ProxyHelper in javac.jar and
hence it now works for me, thanks. However there is another issue,
javac.jar has to be added to the runtime (because the runtime also
needs ProxyHelper).

Cheers,

 -- Howard.
