Elytron SASL factories don't follow contract from corresponding Java interfaces ------------------------------------------------------------------------------- Key: ELY-788 URL: https://issues.jboss.org/browse/ELY-788 Project: WildFly Elytron Issue Type: Bug Reporter: Josef Cacek Assignee: Jan Kalina Priority: Blocker Labels: sasl Java [SaslClientFactory|http://docs.oracle.com/javase/8/docs/api/javax/security...] and [SaslServerFactory|http://docs.oracle.com/javase/8/docs/api/javax/security...] interfaces define where {{null}} parameters or {{null}} return values are allowed and which Exception types can be used in methods. Elytron implementation of SASL mechanisms doesn't follow this contract, which results in NullPointerExceptions. E.g. {code} java.lang.NullPointerException at org.wildfly.security.sasl.scram.ScramSaslClientFactory.getMechanismNames(ScramSaslClientFactory.java:119) ... {code}
