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 server is reloaded. Even running GC can't stop that observation. Maximum is continuosly rising. When I stop reloading server new maxima are not reported anymore. Increasing trend can be seen also in jconsole diagrams.
Similar behaviour can be seen in EAP8. In EAP 74 the trend is much steeper, so maybe there is also different leak.
