             Summary: MathParseException when parsing fractions on Android
                 Key: MATH-1395
                 URL: https://issues.apache.org/jira/browse/MATH-1395
             Project: Commons Math
          Issue Type: Bug
            Reporter: Brian Zable


I'm seeing a strange issue when trying to work with the Fraction classes on 
Android. In my tests, which are standard JUnit tests, the following code 
performs flawlessly;

{code:java}
String amount = "1 1/2";
ProperFractionFormat ff = new ProperFractionFormat();
Fraction f = ff.parse(amount.trim());
{code}

However, at run time in an Android application, the same code throws an 
Exception:
{noformat}
                   Caused by: 
org.apache.commons.math3.exception.MathParseException: illegal state: string "1 
1/2" unparseable (from position 3) as an object of type 
org.apache.commons.math3.fraction.Fraction
                      at 
org.apache.commons.math3.fraction.FractionFormat.parse(FractionFormat.java:199)
{noformat}

I am testing on a Nexus 5X emulator with API level 23 for reference.
