Provide do-nothing no-arg constructor or not ?

[Tom Zeller]

Should I remove the do-nothing no-arg constructor from OpenSAML's
AbstractProfileAction now that I have removed the one and only call to
setId(getClass().getName) ?

On a dev call, I thought we talked about whether or not to let the
compiler automatically provide a default constructor, but I do not
remember what we decided.

I retained the do-nothing no-arg constructor, because I thought that
was the right thing.
