JWS offline-allowed connectionException

FULL PRODUCT VERSION :
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Versión 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
When using offline-allowed with shortcut online="true" there are cases where it doesn't work as expected in the specs.
I can delete the WAS server folder containing the jnlp and .jar files without any problem, it load them from the cache (as expected), I can disconnect my computer from the network and it loads from the cache, updatings are working perfect... but If I disconnect the WAS service daemon from the machine (or I modify my hosts file to point the url to an unexistent ip or localhost) it doesn't load from the cache and I got a ConnectException in the launcher



jnlp file with:

(...)
 <shortcut online="true" install="true">
      <desktop/>
      <menu submenu="XXXX">
       <menu submenu="XXXX"/>
      </menu>
    </shortcut>
    <offline-allowed/>
  </information>

and the update check tried with all combinations like:

 <update check="always" policy="always">

or

<update check="timeout" policy="prompt-run"/>,

<update check="background" policy="always">

and anyone works in this case

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
load application with jnlp like our jnlp, then modifying local computer host file to resolve the url to 127.0.0.1 (without a WAS sever) or to an unexistent ip if you can't shutdown server or disconnecting it from the network

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It should ignore the ConnectException and load the app from cache as in another cases like when I remove the folder from the server
ACTUAL -
ConnectException in Launcher causing to not load from Cache
