I have a simple demo which can do some MS office automation like create Outlook email item and create Word documents, basically my code is following the example from: https://github.com/java-native-access/jna/tree/master/contrib/msoffice .

The example code works fine with JNA 4.1.0, but when I update JNA to latest 4.2.1 release, it's broken.

I get the following exception:

Exception in thread "main" com.sun.jna.platform.win32.COM.COMException: A null reference pointer was passed to the stub. (puArgErr=)
 at com.sun.jna.platform.win32.COM.COMUtils.checkRC(COMUtils.java:112)
 at com.sun.jna.platform.win32.COM.COMUtils.checkRC(COMUtils.java:95)

 at testjna.MSOfficeDemo.<init>(MSOfficeDemo.java:21)
 at testjna.MSOfficeDemo.main(MSOfficeDemo.java:13)

following the error it comes from the native code. does anyone encountered the same problem?

Thanks.

Open a bug please to start. There were a lot of code changes and a lot of this doesn't run through test automation because we don't always have office around. If you have time, run the tests, see if there's anything obvious.

Logged an issue against this problem, will run more test later.

Hi,

I feel vaguely responsible for this, as I've done a lot of work around COM lately. Flying back to Canada on tuesday, will take a look at this next week.
