减少相同异常的记录

Question

有没有什么聪明的方法可以减少"等于"异常的记录？

例如:

java.lang.IllegalArgumentException: Wrong parameter, should be a float from 0 to 100
at com.test.Foo.setAmount(Foo.java:93)
at com.test.Bar.setAmounts(Bar.java:39)
at com.test.Bar2.init(Bar2.java:152)
at java.awt.event.InvocationEvent.dispatch(Unknown Source) [na:1.7.0_65]
at java.awt.EventQueue.dispatchEventImpl(Unknown Source) [na:1.7.0_65]
at java.awt.EventQueue.access$200(Unknown Source) [na:1.7.0_65]
at java.awt.EventQueue$3.run(Unknown Source) [na:1.7.0_65]
at java.awt.EventQueue$3.run(Unknown Source) [na:1.7.0_65]
at java.security.AccessController.doPrivileged(Native Method) [na:1.7.0_65]
at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Source) [na:1.7.0_65]
at java.awt.EventQueue.dispatchEvent(Unknown Source) [na:1.7.0_65]
at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) [na:1.7.0_65]
at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) [na:1.7.0_65]
at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) [na:1.7.0_65]
at java.awt.EventDispatchThread.pumpEvents(Unknown Source) [na:1.7.0_65]
at java.awt.EventDispatchThread.pumpEvents(Unknown Source) [na:1.7.0_65]
at java.awt.EventDispatchThread.run(Unknown Source) [na:1.7.0_65]

在特定情况下,这种异常可以每秒抛出90次.我们使用AWT处理程序来记录异常,它可以"冻结"所有Swing的应用程序.

我想到的第一个解决方法是在不同的线程中记录异常,但是这样的approch在以后的调试中可能是一个真正的地狱.

第二个想法是将异常放在WeakHashMap中,并仅在第一次出现时记录异常.我不知道如何执行异常等于是否足够快.

如果要使用Logback,则会有一个名为DuplicateMessageFilter的过滤器在重复一段时间后丢弃消息.
