Java 7 introduced the @SafeVarargs compiler annotation to suppress certain warning messages when invoking a varargs method (a method with a variable number of arguments). Also, as pointed out on Web pages such as "Changes in access of variables for generic classes in Java 7" (http://stackoverflow.com/questions/10782876/changes-in-access-of-variables-for-generic-classes-in-java-7), certain generics-oriented code that compiled under Java 6 no longer compiles under Java 7. As far as I know, this is the extent of generics changes.
All the best.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
