Coerces an object to a specific type according to the EL type conversion rules. An {@link ELException} is thrown if an error results from applying the conversion rules. @param obj The object to coerce. @param targetType The target type for the coercion. @return the coerced object @throws ELException if an error results from applying the conversion rules.
