B4J Question Java Code Failing in stand alone package

[MrKim]

Reference this thread

This the code that fails in stand alone package:

   Dim jo As JavaObject
   jo.InitializeStatic("java.awt.Toolkit")
   Dim toolkit As JavaObject = jo.RunMethod("getDefaultToolkit", Null)
   toolkit.RunMethod("beep", Null)

Basically the a B4XFloatTextField is expecting a certain range of keys. This is checked in the TextChanged event and if the key is not one of the expected keys the Beep Routine is called.
Old:, New: and S: are logs of .._TextChanged (Old As String, New As String), and New.SubString(New.Length - 1).

Below is the output when the app is run using run_debug.bat:

C:\AndroidApps\B4X\PWDB\B4J\Objects\temp\build>cd bin
