Cannot specify INTEGRAL as transport-guarantee Type

[hs536]

Servlet 6.0 schema says that we can specify INTEGRAL as the type of transport-guarantee.

refs) https://jakarta.ee/xml/ns/jakartaee/web-common_6_0.xsd

<xsd:complexType name="transport-guaranteeType">
<xsd:annotation>
<xsd:documentation> The transport-guaranteeType specifies that the communication between client and server should be NONE, INTEGRAL, or CONFIDENTIAL. NONE means that the application does not require any transport guarantees. A value of INTEGRAL means that the application requires that the data sent between the client and server be sent in such a way that it can't be changed in transit. CONFIDENTIAL means that the application requires that the data be transmitted in a fashion that prevents other entities from observing the contents of the transmission. In most cases, the presence of the INTEGRAL or CONFIDENTIAL flag will indicate that the use of SSL is required. Used in: user-data-constraint </xsd:documentation>

like

    <security-constraint>
        <web-resource-collection>
           <web-resource-name>integral</web-resource-name>
           <url-pattern>/integral</url-pattern>
        </web-resource-collection>
        <user-data-constraint>
           <transport-guarantee>INTEGRAL</transport-guarantee> ★
        </user-data-constraint>
    </security-constraint>

On the other hand, Exousia uses ServletSecurity.TransportGuarantee in SecurityConstraint (instead of jakarta.security.jacc.WebUserDataPermission).

exousia/impl/src/main/java/org/glassfish/exousia/constraints/SecurityConstraint.java

Line 35 in ebdd1a2

private final TransportGuarantee transportGuarantee;

ServletSecurity.TransportGuarantee does not have INTEGRAL as its API, so we cannot use this type.

I happened to notice this issue when I was testing apps on GlassFish 7(nightly build).
https://github.com/eclipse-ee4j/glassfish/blob/9c73d617fbea80034c57aee9580f62fea9aa7221/appserver/security/core-ee/src/main/java/com/sun/enterprise/security/web/integration/GlassFishToExousiaConverter.java#L50-L54

Unfortunately, it is not detailed in Jakarta Servlet spec...
