Hey @matthewelwell, would you mind checking this out since it's a major version bump?

[matthewelwell]

Hey @beeme1mr, I've just released 6.1.0 of the Flagsmith Java SDK which just replaces TestNG with JUnit so that (for boring reasons) we could test backwards compatibility with Java 8. I guess Renovate should pick this up at some point in the next few hours and update the PR.
