升级Spring Boot和Java版本后出现IllegalReferenceCountException

Question

从我们的服务调用 API 时，我们间歇性地看到以下错误。该问题仅在负载测试期间发生 - 读取传入数据时收到错误。连接将被关闭。

我们将 spring boot 版本从 java 8 升级到 3.0.3 并将 java 版本从 java 8 升级到 17 后，问题开始出现。

我们尝试使用 application.properties 文件以及使用 ExchangeStrategies 来增加缓冲区大小。增加缓冲区大小后，我们发现错误频率有所减少，但错误仍然间歇性地持续存在 -

spring.codec.max-in-memory-size: 20MB

WebClient.builder()
                .exchangeStrategies(ExchangeStrategies.builder()
                        .codecs(configurer -> configurer.defaultCodecs().maxInMemorySize(MAX_BUFFER_SIZE))
                        .build())

我的同一个案例也发生了同样的现象。 你有机会解决它吗？ 到底是什么原因呢？
