bq. While technically it breaks back compatibility, How does it break back compatibility? Generics are only compile time - they simply don't exist in the binary. Java itself is extremely back compat, so you can still use StringBuffer and the rest. I didn't find anything in the archives or the wiki that talks about a back compat break - that I can find anyway ...
