// more then one UNO interfaces, as can be determined by the property
// SUPPORTED_INTERFACES_PROP, then the INTERFACE_ADAPTER_FACTORY creates an object that

// JavaScript passes integer values always as VT_I4. If there is a parameter or
// property of type any then the bridge converts the any's content according
// to "o2u_variantToAny". Because the VARTYPE is VT_I4 the value would be converted
// to TypeClass_LONG. Say the method XPropertySet::setPropertyValue( string name, any value)
// would be called on an object and the property actually is of TypeClass_SHORT.
// After conversion of the VARIANT parameter the Any would contain type
// TypeClass_LONG. Because the corereflection does not cast from long to short
// the "setPropertValue" would fail as the value has not the right type.

// The corereflection does convert small integer types to bigger types.
// Therefore we can reduce the type if possible and avoid the above mentioned
