The following command for the batch-jberet subsystem produces NullPointerException

/subsystem=batch-jberet/thread-factory=thread-factory-edit:add()

with error message

{
"outcome" => "failed",
"failure-description" => {"WFLYCTL0080: Failed services" => {"org.wildfly.threads.thread-factory.thread-factory-edit" => "Failed to start service
Caused by: java.lang.NullPointerException"}},
"rolled-back" => true
}

Setting priority to Blocker as this is a regression against CR1.
