title: IntelliJ IDEA debug jumps inside instead of going over
body: <p>I use last stable SBT with Scala 2.10 and last Scala plugin in IntelliJ IDEA 12.x. And have very simple test Scala project.</p>
  
  <p>I have <a href="http://etorreborre.github.io/specs2/" rel="noreferrer">specs2</a> test where I want to start my debug from. Having several breakpoints, I'm expecting going over lines,  (from one break point to another - in my test and in My code), but instead: the debbuger going somewhere inside library classes, stops there, showing me some strange sources. </p>
  
  <p>That's reproducible all the time, and I have to click 2, 3, sometimes 5 times on the next-arrow-button (on debug panel) to reach next break point (in the test or in the code).</p>
  
  <p>I run my test with SBT 'test-compile' action, like IntelliJ pop-up suggests.</p>
  
  <p>Aldo I found <a href="http://confluence.jetbrains.com/display/SCA/Scala+Debugger+Settings" rel="noreferrer">this</a> debug settings for Scala ("Do not step into specific Scala classes"). But I have this check-box selected.</p>
  
  <p>I've post an <a href="http://youtrack.jetbrains.com/issue/SCL-5637" rel="noreferrer">issue</a> in IntelliJ IDEA site.</p>
