Describe the bug

The JWKSUtils.computeThumbprint(..) does not account for ECPublicJWK keys.

Keys generated or directly parsed as a ECPublicJWK will return incorrect thumbprints.

Version

26.1.4

Regression

[ ] The issue is a regression

Expected behavior

Calculating the thumbprint of a JWK does not depend on the type of its instance.

Actual behavior

The thumbprint depends on whether the same JWK is a JWK or a ECPublicJWK were the latter one is incorrect.

How to Reproduce?

String keyA = "

";

ECPublicJWK ecPublicKey = JsonSerialization.readValue(keyA, ECPublicJWK.class);
JWK publicKey = JsonSerialization.readValue(keyA, JWK.class);

assertEquals(JWKSUtils.computeThumbprint(publicKey), JWKSUtils.computeThumbprint(ecPublicKey));

Anything else?

Pretty sure other subclasses have similar issues.
It would also be worthwile to check if all required members for the thumbprint are present while computing it.
This would prevent similar issues for new subtypes.
