Tristan Tarrant created ELY-1898: ------------------------------------ Summary: ServiceFactory<Credential> used in API is too strict Key: ELY-1898 URL: https://issues.jboss.org/browse/ELY-1898 Project: WildFly Elytron Issue Type: Bug Components: API / SPI Affects Versions: 1.11.0.CR1 Reporter: Tristan Tarrant In several places in the API, `SecurityFactory<Credential>` is used, but its bound is too strict, disallowing passing in specific instances, e.g. `SecurityFactory<GSSKerberosCredential>`. These should all be replaced with `SecurityFactory<? extends Credential>`. An example of code that doesn't work: {code:java} SecurityFactory<GSSKerberosCredential> ksf = ...; CredentialSource cs = CredentialSource.fromSecurityFactory(ksf); // Compiler error: required SecurityFactory<Credential> provided SecurityFactory<GSSCredential> {code} Similar issue in the following method: {code:java} MechanismConfiguration.setServerCredential(SecurityFactory<Credential> credentialFactory) {code} -- This message was sent by Atlassian Jira (v7.13.8#713008)
