JavaClasses - Object required

This VBS code reports Object required: 'JavaClasses'.

sub testPDF
  fileName = "mypath\test.pdf"
  set PDFReport = JavaClasses.org_apache_pdfbox_pdmodel.PDDocument.load_3(fileName) 
End Sub

I was reading PDF files successfully in TC11 (here) even after Java updates (here)

I haven't run this test for a long while and now find that it is broken in TC 12.

I updated the java bridge in Tools \ Options \ Engines \ Java Bridge to point to the current Java VM (C:\Program Files\Java\jre1.8.0_141\bin\server\jvm.dll)

My Java Bridge in Tools \ Current project properties \ Java Bridge is still configured as before "..\pdfbox-app-1.8.12.jar", which I know was working before in TC11.

Java Application Support (File \ Install Extensions \ Desktop \ Java Classes Support) is installed.

Can anyone, who is actually reading PDF files in TC 12, please help shed light on this.

Many thanks.
