Tool https://github.com/check-leak/check-leak works on principle of reporting new maximum of instances per class. After some time report stabilize to this output

This mean those classes reach new occurence maximum each time application is redeployed. Even running GC cant stop that observation. Maximum is continuosly rising.
Overal number of instances match number of redeploys. When I stop redeploying app new maxima are not reported. Increasing trend can be seen also in this diagram of Old Gen Memory Heap area.
