我们的JAVA Swing APPLICATION在PROD中间歇性地为几个用户冻结 .
冻结时的EDT堆栈是：
“AWT-EventQueue-0” - 线程t @ 18 java.lang.Thread.State：在sun.misc.Unsafe.park上等待（本机方法） - 停车等待<1ba06b3>（java.util.concurrent . java.util.concurrent.locks.LockSupport.park（LockSupport.java:175）上的java.util.concurrent.locks.AbstractQueuedSynchronizer $ ConditionObject.await（AbstractQueuedSynchronizer.java:2039）中的locks.AbstractQueuedSynchronizer $ ConditionObject） .EventQueue.getNextEvent（EventQueue.java:608）java.awt.EventDispatchThread.pumpOneEventForFilters（EventDispatchThread.java:170）at java.awt.EventDispatchThread.pumpEventsForFilter（EventDispatchThread.java:116）at java.awt.EventDispatchThread.pumpEventsForHierarchy（ EventDispatchThread.java:105）java.awt.EventDispatchThread.pumpEvents（EventDispatchThread.java:101）at java.awt.SequencedEvent.dispatch（SequencedEvent.java:107）at java.awt.EventQueue.dispatchEventImpl（EventQueue.java:756） ）java.awt.EventQueue.access $ 700（EventQueue.java:97）at java.awt.EventQueue $ 3.run（EventQueue.jav） a：709）java.awt.EventQueue $ 3.run（EventQueue.java:703）at java.security.AccessController.doPrivileged（Native Method）at java.security.ProtectionDomain $ JavaSecurityAccessImpl.doIntersectionPrivilege（ProtectionDomain.java:76）at java.security.ProtectionDomain $ JavaSecurityAccessImpl.doIntersectionPrivilege（ProtectionDomain.java:86）java.awt.EventQueue $ 4.run（EventQueue.java:731）at java.awt.EventQueue $ 4.run（EventQueue.java:729）at java位于java.awt.EventDispatchThread.pumpOneEventForFilters的java.security.ProtectionDomain $ JavaSecurityAccessImpl.doIntersectionPrivilege（ProtectionDomain.java:76）中的.security.AccessController.doPrivileged（Native Method）位于java.awt.EventQueue.dispatchEvent（EventQueue.java:728） （EventDispatchThread.java:201）java.awt.EventDispatchThread.pumpEventsForFilter（EventDispatchThread.java:116）java.awt.EventDispatchThread.pumpEventsForHierarchy（EventDispatchThread.java:105）at java.awt.EventDispatchThread.pumpEvents（EventDispatchThread.java： 101）在java.awt.Eve java.awt.EventDispatchThread.run中的ntDispatchThread.pumpEvents（EventDispatchThread.java:93）（EventDispatchThread.java:82）
下面似乎是最接近的匹配：invokeAndWait seems to cause the application to freeze intermittently
我怀疑 ModelDialog 在某种程度上取代 eventQueue 并且 EventDispatch 仍在观看旧的 eventQueue 所以它没有醒来并处理事件 . 但这在测试程序中是不可重现的 .
欢迎任何建议或意见 .
