> Java 7 changed the warnings a little bit:
> - Java 6 only knew "unchecked" warning type, applying for all types of generics violations,
like missing generics (raw types)
> - Java 7 still knows "unchecked" but only emits warning if the call is really unchecked.
Declaration of variables/fields or constructing instances without type param now emits "rawtypes"
warning.
> The changes above causes the Java 7 compile now emit lots of "rawtypes" warnings, where
Java 6 is silent. The easy fix is to suppres both warning types: @SuppressWarnings({"unchecked","rawtypes"})
for all those places. Changes are easy to do, will provide patch later!
