FULL PRODUCT VERSION :
java version "1.7.0_06"

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]
  Bug occurs on all OSs tested so far: Win7, WinXP

A DESCRIPTION OF THE PROBLEM :
Application works as expected when "online" i.e. with an internet connection, but fails when "offline" i.e. with no internet connection:

JNLPClassLoader: Finding library jspWin.dll
java.net.ConnectException: Connection timed out: connect
at java.net.TwoStacksPlainSocketImpl.socketConnect(Native Method)
at java.net.AbstractPlainSocketImpl.doConnect(Unknown Source)
        ...

java.lang.UnsatisfiedLinkError: no jspWin in java.library.path: Check that native library jspWin is in proper directory


This is a regression - it works on Java6, Java5, Java4.

REGRESSION. Last worked in version 6u31

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Get http://driveweb.com/tech/ap/v3/dw.jnlp
After launch, etc., choose menu item 'Directory->Discover on Serial Port->PL-series DC drive'

When online, it works, when offline it fails.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A dialog appears which would allow connection via a serial port
ACTUAL -
An exception occurs (and is reported via a dialog).
