             Summary: 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
            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}
