An example failure from JBEAP-6887:

{
    "outcome" => "failed",
    "failure-description" => {
        "WFLYCTL0080: Failed services" => {"org.wildfly.security.credential-store-client.cs_not_found_exception" => "org.jboss.msc.service.StartException in service org.wildfly.security.credential-store-client.cs_not_found_exception: WFLYELY00004: Unable to start the service.
    Caused by: org.wildfly.security.credential.store.CredentialStoreException: ELY09506: Cannot read credential storage file '/home/hsvabek/securityworkspace/VERIFICATION/2016_11_02_UX_testing/jboss-eap-7.1.0.DR7/standalone/data/cs/keystore-not_exists.jceks' for the store named 'cs_not_found_exception'
    Caused by: java.io.FileNotFoundException: /home/hsvabek/securityworkspace/VERIFICATION/2016_11_02_UX_testing/jboss-eap-7.1.0.DR7/standalone/data/cs/keystore-not_exists.jceks (No such file or directory)"},
        "WFLYCTL0412: Required services that are not installed:" => ["org.wildfly.security.credential-store-client.cs_not_found_exception"],
        "WFLYCTL0180: Services with missing/unavailable dependencies" => undefined
    },
    "rolled-back" => true
}

There is no requirement not to show an exception or stack trace snippet. IMHO it's the best part of the message. And it's not feasible to show nothing else, as there are a number of layers in between.

But, this can certainly be improved, which is what this issue is about:

1) "WFLYCTL0180: Services with missing/unavailable dependencies" => undefined

This is just noise. I'm quite certain this is already fixed and verified in a different issue though. Reproducing this against current code doesn't show this bit any longer.

2) "org.jboss.msc.service.StartException in service org.wildfly.security.credential-store-client.cs_not_found_exception: "

This is superfluous, since it follows ""WFLYCTL0080: Failed services" => {"org.wildfly.security.credential-store-client.cs_not_found_exception"" which says the same thing. This can go.

3) ""WFLYCTL0412: Required services that are not installed:" => ["org.wildfly.security.credential-store-client.cs_not_found_exception"]"

Seems redundant since the only non-installed service listed is the one already reported as failed. This I'm not certain I'll fix as doing so may introduce some other issue. But I'll have a look.
