/**
 * CompatibilityAbstractInternalAntlrParser provides backward compatibility for parsers compiled on Xtext >= 2.22
 * but executing on Xtext < 2.22
 *
 * Xtext 2.22 added the overload method setWithLastConsumed(EObject, String, boolean, String) avoiding the
 * need for callers to box the boolean argument. However on earlier platforms the missing new method gives a
 * NoSuchMethodError. CompatibilityAbstractInternalAntlrParser should therefore be inserted as the super class
 * to provide the missing signature.
