Comments
With the integration of JEP 252 to JDK9, CLDR locale data is now the default locale data, which is different from the legacy locale data in JDK8 and prior. If the submitter wants to work around this, they will need to use the legacy locale data explicitly by specifying "java.locale.providers" system property with "JRE,SPI".

CLDR locale data uses U+00A0 NO-BREAK SPACE between digits and '%', while the legacy locale data uses the regular space.

1. Run the attached example (Example.java) 2. Checked this for JDK 8u45, 8u60 ea b23, 9 ea b72. 3. Ouptput with (JDK 8u45): > java Example [49, 48, 48, 32, 37] (9 ea b72): > java Example [49, 48, 48, -96, 37] 4. This issue is reproducible with JDK 9 ea b72 as reported by the submitter.
