The problem of static methods was not the issue I was talking about.
Static methods are there you can use them or not, OGNL supports calling static
methods.The struts team decided to disable this feature.Lots of framework
users, use this feature ( may be they have set -Xmx .. parameters or not) But
they are using it. Let them decide if they should use static method or not.
Now:
If some one decide to use static method call in validators or JSPs)
Is it good to have a method in Action Supports which can be used to help faster
integration and mean while enable users to call static method envocation in
action and JSPs ?!

No
*Unless* you configure app to implement max heap -Xmx2048M -XX:PermSize=2048M
-XX:MaxPermSize=2048m
dont declare any entity Static anything .statics are notorious for parking in
Permgen
where of course the accumulation of other statics will eventually cause OOM
