jsp-configuration: check-interval has invalid default

In jsp-configuration resource-description gives.

"check-interval" =>

{ "type" => INT, "description" => "Check interval for JSP updates using a background thread.", "required" => false, "default" => 0, "access-type" => "read-write", "storage" => "configuration", "restart-required" => "no-services" }

,

Setting that attribute to 0 gives:

12:48:40,565 ERROR [org.jboss.as.controller] (HttpManagementService-threads - 47) Operation ("write-attribute") failed - address: ([

{"subsystem" => "web"}

,

{"configuration" => "jsp-configuration"}

]) - failure description: "JBAS014708: 0 is an invalid value for parameter check-interval. A minimum value of 1 is required"

Side note: no unit is given - what does 1 mean? each ms?
