CVnot opened a new issue, #12111: URL: https://github.com/apache/dubbo/issues/12111
最近线上出现了ConcurrentModificationException异常，dubbo版本是2.7.12 dubbo链路是这样的，上游dubbo服务同步调用我们dubbo服务，我们的dubbo服务作为消费者再异步去调用下游的服务； 类似这个issue：https://github.com/apache/dubbo/issues/6240 我们怀疑是RpcServerContext ThreadLocal中的对象是被多个线程共享了，但是我们的代码没有任何地方使用这个，所以目前没啥思路，提到社区看看大家有没有什么解决思路，或者有类似的问题，感激不尽。  上游dubbo消费端(DubboInvoker)获取到的堆栈如下： Failed to invoke remote method: query, provider:...., cause: java.util.concurrent.CompletionException: java.util.ConcurrentModificationException java.util.concurrent.CompletionException: java.util.ConcurrentModificationException at java.util.concurrent.CompletableFuture.encodeThrowable(CompletableFuture.java:292) at java.util.concurrent.CompletableFuture.completeThrowable(CompletableFuture.java:308) at java.util.concurrent.CompletableFuture.uniWhenComplete(CompletableFuture.java:769) at java.util.concurrent.CompletableFuture.uniWhenCompleteStage(CompletableFuture.java:778) at java.util.concurrent.CompletableFuture.whenComplete(CompletableFuture.java:2140) at org.apache.dubbo.rpc.AsyncRpcResult.whenCompleteWithContext(AsyncRpcResult.java:195) at org.apache.dubbo.rpc.protocol.FilterNode.invoke(FilterNode.java:81) at org.apache.dubbo.rpc.protocol.dubbo.DubboProtocol$1.reply(DubboProtocol.java:146) at org.apache.dubbo.remoting.exchange.support.header.HeaderExchangeHandler.handleRequest(HeaderExchangeHandler.java:100) at org.apache.dubbo.remoting.exchange.support.header.HeaderExchangeHandler.received(HeaderExchangeHandler.java:175) at org.apache.dubbo.remoting.transport.DecodeHandler.received(DecodeHandler.java:51) at org.apache.dubbo.remoting.transport.dispatcher.ChannelEventRunnable.run(ChannelEventRunnable.java:57) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at org.apache.dubbo.common.threadlocal.InternalRunnable.run(InternalRunnable.java:41) at java.lang.Thread.run(Thread.java:748) Caused by: java.util.ConcurrentModificationException at java.util.HashMap$HashIterator.nextNode(HashMap.java:1445) at java.util.HashMap$EntryIterator.next(HashMap.java:1479) at java.util.HashMap$EntryIterator.next(HashMap.java:1477) at java.util.HashMap.putMapEntries(HashMap.java:512) at java.util.HashMap.putAll(HashMap.java:785) at org.apache.dubbo.rpc.AppResponse.addObjectAttachments(AppResponse.java:164) at org.apache.dubbo.rpc.filter.ContextFilter.onResponse(ContextFilter.java:141) at org.apache.dubbo.rpc.protocol.FilterNode.lambda$invoke$0(FilterNode.java:99) at org.apache.dubbo.rpc.AsyncRpcResult.lambda$whenCompleteWithContext$0(AsyncRpcResult.java:197) at java.util.concurrent.CompletableFuture.uniWhenComplete(CompletableFuture.java:760) ... 13 more -- This is an automated message from the Apache Git Service.
