RichDiagnosticFormatter is comparing type variables by their `toString` representation, and in this example the comparison fails due to type annotations. Replacing a call to `stripMetadataIfNeeded` with `stripMetadata` allows the comparison to succeed, and is consistent with the approach used in other parts of RichDiagnosticFormatter (e.g. for [the fix for JDK-8144580](https://github.com/openjdk/jdk/commit/570883e4dc5f769e17b3fcd8f2bbeb369dfe3a5d)).
This got me wondering whether we even need `stripMetadataIfNeeded` at this point, I filed https://bugs.openjdk.org/browse/JDK-8355204 to investigate removing it.
