I added three more engines (Phoenix-Timea and the original Belzebub) to the main Java league (in addition to Java Elite League-4 engines; Java Special League-3 engines and Java Fourth League -16 engines). I still have a few engines that are unplayable in tournaments and matches. Exactly 70 chess engines (in fact projects, engines I have more) written in Java.

The situation after 1916 games:

The situation in my Java main tournament after round 128 (2112 games). A conclusion can also be drawn about the rating of an ex-private engine (Timea 4a18_jet-ja) - engine with an interesting game - never tested by both CCRL & CEGT (I don't know the reason).

After forty consecutive draws, I added HypnoS in a small tournament. Maybe it's more fun. Honestly, I have no idea how this version of Stockfish is the first in Stefan Pohl's UHO-Top15 Engines Ratinglist. Maybe using UHO book? Stockfish 16.1-16-15.1-15 had no problems with Dragon 3.3.

My hunch above is confirmed. All engines in this tournament play linked to a minimalist book: SuperGM_4mvs.abk (8 plies book). I added Berserk 13 to my mini tournament.
