> I've detected that org.apache.axis2.databinding.utils.BeanUtil class can =
be improved for performance. It seems that invoking Introspector.getBeanInf=
o(Class,  Class) takes a lot of time. By caching java.beans.BeanInfo in thi=
s class it doubles up (at least) the performance, especially when returning=
 a big dataset. I changed this myself and saw a great deal of performance i=
