How can ı set jndi-name property on my local jboss modeshape repository named as a "sample" I've just tried, /subsystem=modeshape/repository=sample:add(jndi-name="jcr/sample") code but it fails

{ "outcome" => "failed", "failure-description" => "JBAS014803: Duplicate resource [ (\"subsystem\" => \"modeshape\"), (\"repository\" => \"sample\") ]", "rolled-back" => true }
