Henri Biestro commented on JEXL-292:
------------------------------------

Controlling the Uberspect permitted methods paves the way to a fine control over what can be called from scripts.

> As of now the default implementation of {{internal.introspection.Uberspect}} class does not allow the usage of anything other than default instance of {{internal.introspection.Permissions}} class, althow internally the {{internal.introspection.Introspector}} has a constructor that accesspts the {{Permissions}} object. Subclassing of {{Uberspect}} does not help here since {{Uberspect.base()}} method is decalred {{final}}. We need some way to pass customized {{Permissions}} class to default {{Uberspect}} implementation
