One thing to look at is <apt> processing; I see hints that apt is
properly integrated with the compiler (for which there is now a public API).
We also get a secure console:

This makes me think we need an extended input handler for passwords; the
first impls would support swing and the "legacy" echoing console;
java1.6 could be engaged if present. hmm.
That would fix at least one long-standing bug (if only on Java6) :)
OK, well with the release candiadate, on winxp pro sp2, the new
System.console() feature works. I've done a quick input handler
(ConsoleInputHandler) that will use the secure prompt if a property is set.
My only problem now is how to set the property so that the user can
decide to use the secure prompt or not - any way just for kicks (if
anyone else has Java6 installed)...
org.apache.tools.ant.input.ConsoleInputHandler // perhaps a better name
too...
