>          Components: adb
>    Affects Versions: 1.6.0
>         Environment: Ubuntu 10.04 64-bit, Tomcat 6.0.28, Axis 1.6.0

> 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.)
