Setting sasl-mechanism-selector with some name value in Elytron client configuration file causes NPE during parsing ------------------------------------------------------------------------------------------------------------------- Key: ELY-1119 URL: https://issues.jboss.org/browse/ELY-1119 Project: WildFly Elytron Issue Type: Bug Affects Versions: 1.1.0.Beta39 Reporter: Ondrej Lukas Assignee: Darran Lofthouse Priority: Critical In case when sasl-mechanism-selector is set in Elytron client configuration file then parsing of configuration file throws NPE. For following element (since there is no documentation then I tried to use values "someName", "NONE", "PLAIN" instead of someName): {code} <sasl-mechanism-selector selector="someName"/> {code} is following NPE thrown: {code} ERROR [io.undertow.request] (default task-3) UT005023: Exception handling request to /dep/authenticationContext: java.lang.NullPointerException at
