I watched the Oracle OTN Virtual Event: Java SE and JavaFX 2.0 (28 Feb 2012) and while talking about the new diamond operator (that Map<String, List<String>> myMap = new HashMap<>(); thing) the speaker mentioned that it was not as simpleto implement than one might think, as it is not a simple token replacement.

I'm using Eclipse 3.7 under Java 7, so I want to keep my compiler compliance level in 1.7. By the way, I'm working together with people who use Eclipse 3.6 (which one does not support compliance level 1.7). So although my JRE is JavaSE-1.7, it compiles codes with 1.6 compliance level. The problem is, because the compiler under 1.7 does not support implicit type arguments (diamond), it marks error. For example: List<String> list1 = new ArrayList<>(); // It's recommended in Java 7, but marked as error in Eclipse 3.6 So I hope to set content assist to insert explicit type arguments (old style) rather than implicit type arguments (current style). Is there a way to change how the content assist works?
