when I use spring webflux. discovered a memory leak error related to ByteBuf.release() not being called before it is garbage-collected. The error is traced to the AdvancedLeakAwareByteBuf.writeBytes method, leading to a long chain of method calls involving NettyDataBuffer, AbstractJackson2Encoder, FluxMapFuseable, and many others. The leaked memory is created at PooledByteBufAllocator.newDirectBuffer and results in a large number of write and flush operations in the event loop, ultimately affecting system performance.
Expected Behavior
no leak
Actual Behavior
LEAK: ByteBuf.release() was not called before it's garbage-collected. See https://netty.io/wiki/reference-counted-objects.html for more information.
Steps to Reproduce
sometimes，dont know why and how

Thanks for this report but Spring Boot 2.7.x is not OSS supported anymore. Please upgrade to a supported version.

Thanks for this report but Spring Boot 2.7.x is not OSS supported anymore. Please upgrade to a supported version.
The bug can be fixed by upgrade version to 3.x ?
Comment From: bclozel
@creatorone1 Maybe, we fixed quite a few things since Spring Boot 2.7.4. The latest OSS release for Spring Boot 2.7.x is 2.7.18. Before reporting a bug, you should always be on the latest maintenance version anyway. If you can reproduce this issue with a supported version, we'll have a look.
