> When trying to access public method/field of non-public class via EL I get 
> {noformat}
> java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class X with modifiers "private"
> {noformat}
> This is apparently caused by JDK-4071957 [1], but since that is opened for over 16 years, it should be probably worth it to implement a workaround.
> Workaround for this issue is setting setAccessible(true) on the method before invoking it, thus suppress Java access checking. My guess is it could be done either in BeanELResolver#invokeMethod(...) or BeanELResolver#getMethod(...).
> I have attached a simple reproducer app as well as a stack trace of the exception.
