Reading PDF /PDDocument.load_3 or load not found

Hi,

I have tried to setup PDF reading accoring to instructions found here

https://support.smartbear.com/articles/testcomplete/testing-pdf-files-with-testcomplete/#Extr_Data_pdf

I have java virtualmachine C:\Program Files (x86)\Java\jre1.8.0_131\bin\client\jvm.dll

and I have added pdf-box 1.8.13.jar and classes to project

https://www.dropbox.com/s/16ojffsuzzr53rc/javasettings.PNG?dl=0

In script I get error "Unknown name load_3". same for load and load_2. Code completion works only until 

JavaClasses.org_apache_pdfbox_pdmodel.PDDocument after PDDocument nothing is shown.

But for example code completion in JavaClasses.org_apache_pdfbox_util.PDFTextStripper  shows three instances of NewInstance?

What is wrong here? My code is quite simple

function LoadPdf( FileName );
var 
  docObj;
begin
  docObj := JavaClasses.org_apache_pdfbox_pdmodel.PDDocument.load_3( FileName );
  result :=  docObj;
end;

I have TestComplete 12.

thanks,

mika
