> This PR addresses both [JDK-8314423](https://bugs.openjdk.org/browse/JDK-8314423) and [JDK-8314216](https://bugs.openjdk.org/browse/JDK-8314216), since both are relevant to checks around the structure of switch in the relevant method in `Check`. Additionally a check was needed in `analyzePattern` to detect that when a case starts with a constant case label followed by a `,` or `->` is indeed a constant expression and not a pattern as previously signified.
