EL cannot access public methods/fields of non-public classes

When trying to access public method/field of non-public class that implements public interface via EL I get

java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class X with modifiers "private"

E.g. accessing Collections.unmodifiableList(..).size() via EL will throw the exception, because #unmodifiableList returns non-public implementation of List interface.
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.

I have attached a simple reproducer app as well as a stack trace of the exception.
