Java 性能测试期间CXF中的ConcurrentModificationException
性能测试期间发现以下异常 CXF v3.0.0 jdkv1.8.92 policyinterceptor.java:74是以下代码：Java 性能测试期间CXF中的ConcurrentModificationException,java,cxf,Java,Cxf,性能测试期间发现以下异常 CXF v3.0.0 jdkv1.8.92 policyinterceptor.java:74是以下代码： Policy p = (Policy)msg.getContextualProperty(PolicyConstants.POLICY_OVERRIDE); 看来拦截器试图操纵Hashmap数据（使用交换？） 我们已经在使用此选项： getRequestContext().put("thread.local.request.context", "true");
Policy p = (Policy)msg.getContextualProperty(PolicyConstants.POLICY_OVERRIDE);
getRequestContext().put("thread.local.request.context", "true");

更新 此问题已移至“暂停”： 寻求调试帮助的问题（“为什么此代码不起作用？”） 必须包括所需的行为、特定的问题或错误以及 在问题本身中复制它所需的最短代码。 没有明确问题陈述的问题对其他人没有用处 读者。请参阅：如何创建一个最小的、可复制的示例。” 这个问题不是“为什么这个代码不工作？”。这个问题是“为什么这段代码不能在非常特定的情况下工作，在依赖项的某个地方出现异常？”特定的情况是性能测试。在所有其他情况下，该代码工作正常 “复制所需的最短代码”是一个问题，因为性能测试是在真实系统上进行的测试，所以没有任何代码可以复制。无论如何，我试图复制它，但没有运气 所以我仍然认为原始问题有足够的上下文和描述。
顺便说一句，尽管周末有人问我这个问题，我还是得到了两张赞成票 我的猜测是，由于性能测试中的消息对其进行了猛烈攻击，导致它仍然试图在处理第一条消息时，在处理第二条消息时重新加载缓存。也许可以尝试修改您的性能测试，在释放torrent之前缓慢地触发前六条消息（并在发布过程中执行类似操作）@racraman这是有道理的。我们会检查这个案子。谢谢
