That works in DR11 without issue

Here is implementation of used custom prncipal transformer
{code:java|title=AddCustomPrincipalTransformerImpl.java}
package org.wildfly.extras.creaper.commands.elytron.mapper;

import org.wildfly.extension.elytron.Configurable;
import java.security.Principal;
import java.util.Map;
import org.wildfly.extension.elytron.capabilities.PrincipalTransformer;

public class AddCustomPrincipalTransformerImpl implements PrincipalTransformer, Configurable {

    @Override
    public Principal apply(Principal p) {
        return p;
    }

    @Override
    public void initialize(Map<String, String> configuration) {
        if (configuration.containsKey("throwException")) {
            throw new IllegalStateException("Only test purpose. This exception was thrown on demand.");
        }
    }

}
{code}
