Memo for myself.
Now this throws an exception. With Guava's LoadingCache, the exception surfaces as ExecutionException in publicKeyCache.get in verifySignature method. This verifySignature method wraps it as VerificationException. The verify method catches VerificationException, logs the SEVERE-level message, and returns false.
With this change the LoadingCache now stops caching failure result. A potential problem would be the library users calling the verify method repeatedly in a situation where the certificate location is inaccessible. From the caller's perspective, the result (getting false) remains the same. In that case IdTokenVerifier$PublicKeyLoader logs the warning message. The user can easily tell the problem. This should be fine.

Yep, had similar thoughts on this

Fixes idtoken verifier so that it will not cache empty entries in cases of intermittent problems accessing the keystore
Also, it makes the payload verification protected so child classes can use it separately in case they do signature verification themselves
Fixes #891 ☕️
