Dunno how this slipped by us for so long: | protected <T> T assertInstanceOf(Object o, Class<T> expectedType, boolean allowNull) | { | if (expectedType == null) | fail("Null expectedType"); | | if (o == null && allowNull) | return null; | | try | { | return expectedType.cast(o); | } | catch (ClassCastException e) | { | fail("Object " + o + " of class " + o.getClass().getName() + " is not an instanceof " + expectedType.getName()); | // should not reach this | return null; | } | } | What about if allowNull == false and o == null? :-( A test for test required. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4137790#...
