title: Remove java exception breakpoints when debugging Liferay in eclipse
body: <p>By debugging of Liferay Portal, that is tomcat application, eclipse make usual stop at <code>ThreadPoolExecutor$Worker.run() line: 912</code> although I don't set a breakpoint at this class. The <code>ThreadPoolExecutor</code> isn't a class of my application, I think that belongs to tomcat. My Question is: what is wrong here, and why eclipse stopt here?
  And is it possible to set such "external breakpoints" in eclipse to ignore?</p>
