Should we make it a class for the time being?

[lordofthejars]

Probably when we rewrite everything this would be a class, but for this release I would leave as is

[bartoszmajsak]

But now we have interface with default methods which effectively makes it a class...

[lordofthejars]

Well actually some tests are implementing this interface for testing purposes, so changing to class requires also a rewrite of the tests. Also if next week we work on rewriting this part, would means change the tests again so it is like in one week do the same task twice.

How long the "reimplementation" will take?

[lordofthejars]

No idea, it depends on how far we want to go. Maybe two days between designing reimplementing and testing

[bartoszmajsak]

Ok, let's open an issue describing our findings for refactoring and refer to #165 so we can have a trace of ongoing effort. Can you take care of it?

[lordofthejars]

This issue is just a workaround, the final solution should be implemented as described in #187
