Yes, the two different Issue types definitely adds to the confusion, but we also have the `::issues` method that takes two booleans. It has three callers and only one of those sets the parameters true. This should just have been split into different methods. As it is now, they are calling each other in a circle, only saved by the boolean being false in the second call. Untangling this would make it pretty straightforward to provide a JdkVersion argument to the method for getting just CSR issues.

I think there is value in only calling `BotUtils.getVersion(pr)` once as it's quite expensive to evaluate.
