----------------------------------------
Attachment: ReflectionTest.java
Attached program illustrates performance gains by using cglib for doing reflection calls
Output
Run1 time=11218ms
Run2 time=766ms
Run3 time=109ms
It is more than 7 times faster
(JDK 1.5, Windows, cglib 2.1.3)

> Add reflection bytecode optimization in JBoss EL.
> It could be done optional (as in Hibernate)
> Even on JDK 5 cglib FastClass performs reflection calls faster.
> EL is used heavily during render phase and it is critical that it is optimized for performance.
