      My god. How incompetent can one be: they provide a constructor for configuring the load factor, but they provide no means to querying it. So if a hashset instance shall be transformed to another context and back (e.g. persistence), what is one supposed to do? Ignore the load factor and change the program behavior? What harm would it do to add an implementation-specific getter?

      Not to mention the set wraps a map internally which is THE most moronic thing to do both memory- and performance-wise.

      So another hack method has to provide basic functionality that is missing in the JDK. And should they ever get the idea to implement the set properly, this method will break.

      Parameters:
