Jenkins no longer appears to shutdown correctly

Start Jenkins with java -jar jenkins-2.0-beta-1.jar on windows

In the console hit ctrl+c

expected behaviour

Jenkins does a graceful shutdown and this is appropriately logged

actual behaviour

it appears as though Jenkins is brutally terminated and does not do a graceful shutdown.
There are no logs to indicate a graceful termination

In 1.x I see the following logs
Mar 31, 2016 12:02:39 PM winstone.Logger logInternal INFO: JVM is terminating. Shutting down Winstone

in 2.x I do not see those entries - and there is nothing to indicate in the log that Jenkins is shutting down gracefully
