Hi, Jeff,
There was an important omission in the release notes, namely, that
System.out, System.err, and System.in have been deprecated in favor
of x10.io.Console.OUT, x10.io.Console.ERR, and x10.io.Console.IN,
respectively.
We apologize for the confusion. A new version of the 1.7.3 release
(with just the change to the release notes) will be uploaded to
the X10 release sites shortly.
