      When I want to define own Custom Elytron Provider through modification of Java security provider configuration I got exception about NoClassDefFoundError on CustomImplementation class. But this class is located in same jar file as Custom Elytron Provider.

      I need it to define provider-name in credential-store. Is there some additional step which I missed?

      Jar file is attached and it is same one as here https://issues.jboss.org/browse/JBEAP-8238 from pskopek@redhat.com
