Description

Hi all,

I have found a compatibility-problems between Axis 1.1 and 1.2RC3.
When you use xsd:integer in your wsdl, axis maps it to java.math.BigInteger.
java.math.BigInteger provides a method getLowestSetBit() that leads axis to the
erroneous attempt to write an attribute "lowestSetBit" to the xml it serializes.
I have provided a little patch that prevents axis from serializing any attributes it finds
in objects of classes that extend java.lang.Number (like many wrapper-classes of simple types).

btw: under which circumstances can this be false:

if (propertyDescriptor != null && !(value instanceof SimpleType))

how can e.g. java.lang.Integer be an instance of org.apache.axis.encoding.SimpleType?

bye

Daniel
