Hi

I am running a BANanoServer example from a template.

There is nothing that I have added yet. This is the error i am getting when I compile

                      ^

  where CAP#1 is a fresh type-variable:
    CAP#1 extends javax.servlet.Filter from capture of ? extends javax.servlet.Filte

Any advice.

Thanks in advance...
