Caching BeanInfo in adb module's BeanUtil improves performance

                 Key: AXIS2-4524
                 URL: https://issues.apache.org/jira/browse/AXIS2-4524
             Project: Axis 2.0 (Axis2)
          Issue Type: Improvement
          Components: adb
    Affects Versions: 1.5
            Reporter: Valgeir Halldórsson


I've detected that org.apache.axis2.databinding.utils.BeanUtil class can be 
improved for performance. It seems that invoking 
Introspector.getBeanInfo(Class,  Class) takes a lot of time. By caching 
java.beans.BeanInfo in this 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 improvement.
