org.jose4j.jwt.consumer.JwtConsumerBuilder throwing NullPointerException

[Former user]

jwtConsumer = new org.jose4j.jwt.consumer.JwtConsumerBuilder().setSkipDefaultAudienceValidation().setVerificationKey(publicKey).build();

jwtClaims = jwtConsumer.processToClaims(jwt);

From the above lines of code, this line "jwtClaims = jwtConsumer.processToClaims(jwt);" is throwing NullPointerException.

Can someone help me in knowing why NullPointerException is coming.

I'd need more info before I could even venture a guess, like: jose4j version, the full stack trace and the jwt string.

jose4j isn't in stack trace anywhere. The NullPointerException looks to be thrown from some other code. Not much more I can say.

Also there never was a 0.4.5 version of jose4j so not sure where that's coming from. But it suggests you're maybe using a pretty old version and you might want to consider using the newest version.
