Our codebase has tons of Java generics warnings, including:
legacy code before JDK5's generics feature is introduced;
some generics warnings are inevitable.
This ticket aims to get rid of Java generics warnings as much as possible. As demonstrates, Java generics warnings could lead to serious runtime exception. Getting rid of Java generics warnings is still highly relevant.
Given v6's current status before official release, it is a good timing to do such clearing up to pave the way for a long easier maintenance future.
This ticket is ambitious and it would involve lots of efforts. Time will tell that it is worthwhile.
