In "BreakingNews", an "OR" is used to enforce: "The 30-pound baby wasn't born in South Amboy or New Hope."
That should probably be "AND" instead, as in:

NOT BornIn(SouthAmboy OR NewHope) <=> AND( NOT BornIn(SouthAmboy), NOT BornIn(NewHope))

If it is a bug, the Scala version of the example has the same bug.

Hi,

Yes, you are right.

Thanks for the bug report.

best,
Radek

Obviously there is the same mistake since it has been re-coded from Java version.
