adding Security Domain children(Authentication,Authorization,Audit,Mapping) by json not working.

-'Add' operation for Security Domain children(Authentication,Authorization,Audit,Mapping) 'fails with JBAS014746: login-modules may not be null'. The fail message is for Authentication specifically ..but the other nodes fail with matching provider-modules not be null,etc.

• Assumes there is a securityDomain of name 'testDomain3' with cache-type='default'.

-Once the Security Domain child does exist 'read-attribute' and 'write-attribute' operations work as expected via json. This indicates to me that the json values for 'login-modules' is sound but just not acceptable because of a bug.

• The same 'add' operation, see below, via cli completes successfully.
  /subsystem=security/security-domain=testDomain3/authentication=classic:add(login-modules=[{"code"=>"SecureIdentity","flag"=>"required","module-options"=>{"bindDn"=>"uid=ldapSecureUser,ou=People,dc=redat,dc=com"}}])

• This is what the json contents look like before being sent off to the server. Switching 'add' to 'write-attribute' works correctly once the node already exists.:
  {
  "operation" : "add",
  "address" : [ { "subsystem" : "security" }

  ,

  { "security-domain" : "testDomain3" }

  ,

  { "authentication" : "classic" }

  ],
  "name" : "login-modules",
  "value" : [

  Unknown macro: { "flag" }

  ]
  }
