Comment 2 Jiri Rechtacek 2012-06-19 07:47:12 UTC 
Invalid calling AU API org.netbeans.api.autoupdate.OperationContainer.add(OperationContainer.java:304) with null parameter.
Comment 3 Jaroslav Tulach 2012-08-28 14:49:28 UTC 
Well, the null comes from AU, I think. This is the ergonomics code:

OperationContainer.OperationInfo<OperationSupport> inf = ocForEnable.add (el);
Set<UpdateElement> reqs = inf.getRequiredElements ();
ocForEnable.add (reqs);

The null must be in reqs set. I bet getRequiredElements should not return set which contains null, right?
Comment 5 Jaroslav Tulach 2012-11-05 14:36:13 UTC 
The javadoc of inf.getRequiredElements() does not mention it can return null. Either the Javadoc needs to say that, or the inf.getRequiredElements () needs to be fixed not to return null (or an element of null in the array). 

As far as I can say FoD is doing nothing wrong.
Comment 6 Jiri Rechtacek 2012-11-06 09:19:41 UTC 
inf.getRequiredElements() should not return a collection with 'null' elements - I  will fix it
