Benjamin Bentmann commented on MNG-3580:
----------------------------------------
bq. but no clue for IBM....
My code snippet was specially crafted to trigger the faulty code path in
Harmony. There might just be a similar bug in the IBM JRE that simply is not
revealed by the test snippet. As far as I can tell after some debugging through
Maven, Maven itself is not inserting nulls into the plugin list so somebody
else seems to do... If you really want to know, you could simply set a break
point on ModelUtils.java:243 and verify the {{results}} list is properly
populated by {{ArrayList.addAll()}}.
