title: Eclipse 4.2.0 / debugger very slow
body: <p>After switching to Eclipse 4.2.0 the debugger seems to be not responable or very very slow. My used Java version is (same as used in Eclipse):</p>
  
  <pre><code>johannes@luna:~/sirix$ java -version
  java version "1.7.0_03"
  OpenJDK Runtime Environment (IcedTea7 2.1.1pre) (7~u3-2.1.1~pre1-1ubuntu3)
  OpenJDK 64-Bit Server VM (build 22.0-b10, mixed mode)`
  </code></pre>
  
  <p>Anyone else encountered the same behavior?</p>
  
  <p>Edit: I have had too many (old) breakpoints (maybe especially breakpoints on checked and unchecked exceptions are especially costly ;-))</p>
