Exception on deserializing empty element with an xsi attribute on non String type.

[chikim79]

#167 fixed the issue with the String type.

It is still happening on a Double type and possibly others.
xsi attribute is giving errors on Double type regardless of the existence of the value.
e.g. xsi:nil="false" with value and xsi:nil="true" with empty value.

<a xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
       <b/>  <!-- works fine -->
       <c xsi:nil="false">0920</c> <!-- works fine -->
       <d xsi:nil="true"/> <!-- fixed in 2.7 -->
       <e xsi:nil="false">1.2</c> <!-- throws exception -->
       <f xsi:nil="true"/> <!-- throws exception -->
</a>

public class A {
    String b;
    String c;
    String d;
    Double e;
    Double f;
    ...
}

Thank you for reporting this. I hope this can be fixed; there are some special translations done for String handling, but it should be possible to figure out something similar for other simple scalar types: numbers, coolean.

BigDecimal ends up the same. Any updates on this?

@nyilmaz PRs welcome.

Created #354 for general support of xsi:nil.
