Description

BeanUtils.populate fails with "java.lang.IllegalArgumentException: argument type
mismatch" when assigning strings containing integer values (like "123"), if they
are converted through DoubleLocaleConverter, because DecimalFormater.parse()
returns Long and not Double when possible.

My fix is:

DoubleLocaleConverter.java:

protected Object parse(Object value, String pattern) throws ParseException

{ Number result = (Number) super.parse(value, pattern); return new Double(result.doubleValue()); }
