i did some debugging and i think i have found the reason for my issue.
i could see that in
GradleTestPattern my classname was not properly parsed. Reason for that was that one of our packages contained an uppercase char and that the parse logic seems to assume that this is never the case (aware that its recommended to name packages lower case only). Seems that the parse logic change was introduced with v5.5.1
this
So this explains why i was seeing the mentioned behaviour while using 5.5.1
I will rename our packages
