tools/launcher/DiacriticTest.java failed on MacOSX: Input length = 1

The only information about why the test failed is:

Test threw exception: java.nio.charset.UnmappableCharacterException: Input length = 1

There is no core, no hs_err, no flight recording, no nothing.

Priority justification:
ILW = MLH => P4 (Very uncertain)
