@philwebb, I have already tried the same app with 2.2.10.BUILD-SNAPSHOT and it looks much better. There is a number of wrappers in the heap, but I do not think it will cause problems.
In any case, thank you for the resolution, and I will keep you updated after I get this version live (but it will take me some time).

Hello, I would like to ask why there are so many FinalReference of jarFileWrapper?
I see that we have a lot of FinalReference to jarFileWrapper, which causes YGC to take more than 100 milliseconds.

After we downgraded the spring boot version, YGC only took more than 10 milliseconds
What version were you using and what version did you downgrade to?
Can you provide a small sample that we can use the reproduce the problem?
