tomcat在eclipse中调试时，断点频繁停在threadpoolexecutor

以前有一个很奇怪的问题：当我在调试程序的时候，我什么操作都没有进行，突然debug就停在这了，我感到很奇怪，今天又遇到这种问题了，在网上查了查，原因是：

<pre name="code" class="plain">Typically, the debugger in Eclipse is configured to suspend execution at the location where the exception was thrown, on all uncaught exceptions. Note that the exception might be handled later, lower down in the stack frame and might not lead to the thread being terminated. This would be cause of the behavior observed.</pre><br>  

eclipse在默认情况下勾选了“Suspend execution on uncaught exceptions”，暂停执行未捕获的异常。因此eclipse会把所有未捕获的异常先在ThreadPoolExecutor这个类中暂停。

解决方法：Preferences->Java->Debug，去掉"Suspend execution on uncaught exceptions"
