Unable to run write-attribute in jboss EAP 6.3.3 CLI - java-8

Question

I am trying to run the below java code in my custom app:
I am using JBoss EAP 6.3.3 with Java 1.8.0_92 have also used Java 7. This used to work in JBoss EAP 6.3.2 (java 7)
ccp = new CLICommandParser(standalone + "/subsystem=security/security-domain=EncryptDBPassword/authentication=classic:write-attribute"
+ "(name=login-modules,value=["
+ "{flag=required,code=org.picketbox.datasource.security.SecureIdentityLoginModule,"
+ "module-options=[(username=" + dbUser + "),(password=" + dbPassword + "),(managedConnectionFactoryName=jboss.jca:name=jdbc/fooDS),(service=XATxCM)]}"
+ "])");
ccp.execute(client, true);
The error I get is, the security domain gets security-domain gets added by fails in next line of code mentioned above.
INFONFO: Command executed sucessfully: /subsystem=security/security-domain=EncryptDBPasswordXA/authentication=classic:add

I can however run the same command in JBoss CLI and this works. Is there a change I need to do around the code, seems like patch 3 doesn't like to use "write-attribute" in JBoss CLI.
Any pointers will be grateful.
