Oddly enough,  $ export LANG=C fixed it for the subsequent make clean && make run,
which printed the same 
"Using java runtime at: /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/jr"
message after printing the test results, and carried on.

I think we should document the export LANG=C setting in the Mac OS X section of 
the build README for 7u.
