Description

Service function returns which contain (long) arrays of custom objects degrade performance.

Example (POJO):
SomeCustomType[] myFunc() is a lot slower than String[] myFunc()

Reason:
BeanUtil.getBeanInfo() (modules/adb/src/org/apache/axis2/databinding/utils/BeanUtil.java) is called for each element in the output array, even though they are all the same. (According to http://download.oracle.com/javase/6/docs/api/java/beans/BeanInfo.html the result should be cached but this does not seem to be happening.)
