The french template for the @DecimalMin and @DecimalMax constraints is incorrect. Eng:
javax.validation.constraints.DecimalMax.message=must be less than or equal to {value}
javax.validation.constraints.DecimalMin.message=must be greater than or equal to {value}
Fr:
javax.validation.constraints.DecimalMin.message=doit \u00EAtre plus grand que {value}
javax.validation.constraints.DecimalMax.message=doit \u00EAtre plus petit que {value}
A good translation would be:
javax.validation.constraints.DecimalMin.message=doit \u00EAtre sup\u00E9rieur ou \u00E9gal \u00E0 {value}
javax.validation.constraints.DecimalMax.message=doit \u00EAtre inf\u00E9rieur ou \u00E9gal \u00E0 {value}
