Patch to allow debug level applied to Ant 1.5 alpha.  DebugLevels will
be used only when the modern javac compiler is used.

For some reason, by default, ANT passes -g:none to the compiler and
there is
no way for it's default to be the same as Javacs default which is
as far as I know.
Also, in ANT you only have debug on (all) or off (none), check out the
docs for javac
and you will see it has more options...
I wish ANT would expose these...

Correct me if I'm wrong everyone...but I believe the javac setting
"debug=true" used to be the default for Ant 1.3, but isn't for Ant 1.4.
To get the line numbers back in just do the following :

<javac debug="true" .... />

I guess it probably is best that "debug=true" is no longer the default.
Makes for more efficient and smaller code in my opinion.

I have lost line numbers on stack traces with code compiled with Ant
They used to be there when I compiled with Ant 1.3. Is this a default
setting that has changed, a bug with Ant 1.4, or is it just coincidence
actually caused by something completely different.
