JexlPermissions
If the package disallows JEXL introspection, none of its classes or interfaces are visible to JEXL and can not be used in scripts or expression.

JexlPermissions
If the class disallows JEXL introspection, none of its constructors, methods or fields as well as derived classes are visible to JEXL and can not be used in scripts or expressions. If one of its super-classes is not allowed, tbe class is not allowed either.
For interfaces, only methods and fields are disallowed in derived interfaces or implementing classes.

JexlPermissions
If a constructor is not allowed, the new operator can not be used to instantiate its declared class in scripts or expressions.

JexlPermissions
If a method is not allowed, it can not resolved and called in scripts or expressions.
Since methods can be overridden and overloaded, this also checks that no superclass or interface explicitly disallows this methods.

JexlPermissions
This is a convenience method meant to easily give access to the packages JEXL is
used to integrate with. For instance, using
would extend the restricted set of permissions by allowing the com.my.app package.JexlPermissions.RESTRICTED
