Missing "intializedAt" key in Document object - RepositoryCache() modeshape-jcr-api-3.1.1.Final.jar while setting up repository

Hello - I'm getting error while setting up repository using modeshape 3.1.1.jar -

RepositoryCache() constructor -
Document info = repositoryInfo.getContentAsDocument(); // line 171
Below is the debug hover on info object -
Info -
{ "repositoryName" : "documentation" , "repositoryKey" : "ba2a165" , "sourceName" : "CONTENT" , "sourceKey" : "238a131" , "createdAt" :

{ "$date" : "2015-03-05T19:33:43Z" }

, "intializer" : "c8b44dd0-06de-4a59-b866-aa53f09ac0f9" , "createdWithModeShapeVersion" : "3.1.1.Final" }

After this, the code checks for value of "intializedAt" key to set the initialized variable as true-
if (info.get(REPOSITORY_INITIALIZED_AT_FIELD_NAME) != null)

{ initialized = true; break; }

Since the info object is missing the intializedAt key, the repository is not getting initialized and error is getting displayed -
if (!initialized)

{ LOGGER.error(JcrI18n.repositoryWasNeverInitializedAfterMinutes, name, numMinutesToWait); String msg = JcrI18n.repositoryWasNeverInitializedAfterMinutes.text(name, numMinutesToWait); throw new SystemFailureException(msg); }

Jdk version - 1.7

Do I have to make any specific entries in my standalone for this?

Thanks,
Siddharth
