     [ http://jira.jboss.com/jira/browse/JBSEAM-1977?page=all ]

Mikhail Grushinskiy updated JBSEAM-1977:

    Attachment: ReflectionTest.java

Don't use javassist though. It performs even worse than JDK's reflection

Run1 time=11188ms
Run2 time=672ms
Run3 time=93ms
Run4 time=94ms
Run5 time=17547ms  (Run5 is javassist)

> 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.
