Now you can also access non-primitive types such as AtomicLong

	[standalone@localhost:9990 /] /subsystem=jgroups/channel=web/protocol=FD_ALL:read-attribute(name=getSuspectedMembers
	{
	    "outcome" => "success",
    	"result" => "[]"
	}

PS: I have accidentally put the formatting changes in the same commit, sorry about that but it was quite messy.
