Looks like you have some Checkstyle errors, please run your maven command with the -Pcontrib-check before pushing commits, thanks!

Looks like all of the automated checks have passed - was there anything else that needs to be done before this can be accepted @mattyb149 ?

@markap14 did the work 5955, he would be the best to understand the issue and the side effects, ie. if this is the right fix or there needs to be an additional refactor which includes looking at the original fix again.
