[SDO] validations in SDOUtil.createFromString()

[Amita Vadhavkar]

        Object convertedObj =
org.apache.tuscany.sdo.util.SDOUtil.createFromString(
TypeHelper.INSTANCE.getType("commonj.sdo", "Month") , "abcd");
        System.out.println("conv month "+convertedObj+",
"+convertedObj.getClass().getName());

Is the above supposed to throw some sort of exception as "abcd" is not in
following "--"mm zz?  pattern?

I tried it and it simply gives "abcd" String with no exceptions. Trying to
understand what is the expected behavior.
