In the latest update, ejb3 thread pools now require specifying the time unit for keepalive-time, until now, it has only been a simple number, now it is an object. Trying to create an ejb3 thread pool in admin console will fail:

{
"outcome" => "failed",
"failure-description" => "Attribute keepalive-time expects values of type OBJECT but got 100 of type INT",
"rolled-back" => true
}
