Problem with BSTR OUT parameter (.DLL)

What I've done

  I want to use a .DLL from Java so I decided to use JaWIN.

  I'm using release 'jawin-2.0-alpha1' and I generated the stubs
  with jawinBrowser. I used the resulting stub code in my java project
  and was able to call the .DLL. So far, so good.

However, I ran into errors when calling functions that return a string,
e.g. the function with the following
signature:

  Function GetObjectRelationTypes
  [out] BSTR BSTR List )
  Result: [out, retval] BSTR

The Java code below throws the 'org.jawin.COMException: 80020005: Type
mismatch' exception:

      IASCORSA iascorsa = new IASCORSA(ASCORSA.CLSID);

      String[] list = new String[20];
      boolean suc = iascorsa.GetObjectRelationTypes(list);

Of course the question is: what's wrong?

Below, the execution trace:

What are the possible causes for error?
