It's important that we make sure we are following specs as well as providing a reasonable migration path. Checking the JWS RFC, it states (emphasis mine):
So I agree that this is a bug and can be fixed in time for the 7.0 release. Thanks for spotting it, @namest504! |

Fixed: #18092
The JwtTypeValidator was performing a case-sensitive check for the JWT typ header, which was a change from the behavior of the previous Nimbus JOSEObjectTypeVerifier.
This commit updates the JwtTypeValidator to be case-insensitive.
New test cases have been added to verify this change.
