[I] Dubbo 2.7.12 LFUCache Memory leak bug [dubbo]
GuanghuiCong opened a new issue, #13500:
URL: https://github.com/apache/dubbo/issues/13500
Environment
Dubbo version: 2.7.12
Operating System version: linux
Java version: 1.8
Description
使用dubbo2.7.12版本出现内存泄漏Bug，gc也无法回收，在本地通过有感网关桥调用服务，发现有感在请求时会附带generic=true的参数，在服务端generic=true会先进入GenericFilter的invoke函数(104行，PojoUtils.realize(args, params, method.getGenericParameterTypes()))，做class的序列化，在SerializeClassChecker的validateClass中使用到lfuCache，但是LFUcache存在bug，最终导致内存泄漏。
产生原因：这个 pr [7967 ](https://github.com/apache/dubbo/pull/7967) 导致了该问题
