When using custom type parameters for a Component set in Component Properties > Code > Type Parameters, the generated assignment of the component also calls the type rather than using the diamond operator. For example, when creating a JComboBox which I have extended using "<TweekerParameter>", it is created in the generated code blocks as:

private javax.swing.JComboBox<TweekerParameter> parametersList;

Which is then later assigned as:

parametersList = new javax.swing.JComboBox<TweekerParameter>();

Using the "redundant type arguments in new expression (use diamond operator instead)." as my IDE kindly points out. I'm aware that the diamond operator was only introduced in Java 7, and the code generation may be designed to do this to be properly backwards-compatible, however it would be nice if either the generator detects the version and uses the appropriate assignment, or the editor detects that the code block is generated (via the editor-fold tag) and suppresses the code markings for it (dealer's choice ;-) ).
