Hi,

I am using openhab with the jsr223 scripting engine & jython to do some home automation.
With jython 2.7.1 (latest version from maven) it seems that modules do not get imported properly.

I have two files (A&B) which import a self written library:
   import testModule

In the library I set a property:

   import testModule
   print( 'TESTPROP: {}'.format(hasattr(testModule, 'TESTPROP')))
   testModule.TESTPROP = 'TEST'
   print( 'TESTPROP: {}'.format(hasattr(testModule, 'TESTPROP')))

This results in the following output:

   TESTPROP: 0
   TESTPROP: 1
   
   TESTPROP: 0
   TESTPROP: 1

It seems that the library does get loaded multiple times.
With jython 2.7.0 the output is correct as the library only gets loaded once:

   TESTPROP: 0
   TESTPROP: 1


Steps to reproduce:
- Download Openhab2.3 from https://www.openhab.org/
- Copy Jython Standalone to Openhab2\runtime\lib\boot\
  Use 2.7.1 to reproduce problem, use 2.7.0 to see it work
- unzip attached file into Folder Openhab2\conf\
- Edit Openhab2\runtime\bin\setenv.bat Line 118:
  Insert:
    -Dpython.path=%OPENHAB_CONF%/automation/lib ^
  to add library path to JAVA_OPTS
- Start openhab (start.bat)
- See https://www.openhab.org/docs/tutorial/1sttimesetup.html and select Expert
- Activate JSR223 scripting (Next-Gen Rule Engine)
  https://www.openhab.org/docs/configuration/rules-ng.html#installation
- Stop Openhab and restart and watch output in console window
  Scripts are located in automation/jsr223
  Library is located in automation/lib
