It was always my understanding that <javac>, just like SUN's compiler,
always defaults to the current Java source level for the JDK.

Wrong assumption? The fact that the Java language evolves, making
older sources incompatible with it, is not really pointing to a BC
issue for <javac> IMHO.

Gump moving to 1.5 has got to have consequences, it can't be
transparent, when new keywords and classes are added to the platform
(even new classes can break the source, when it's using import foo.*).
