Unable to set breakpoints in EPIC (Eclipse)
<p>I have installed Epic and Eclipse (I have never used them before). Whenever I try to set a breakpoint, I always get this error:</p>

<blockquote>
  <p>"An internal error occurred during: "Toggle Line Breakpoint (epic)"(Exception: java.lang.NullPointerException)"</p>
</blockquote>

<p>I have updated Eclipse to 3.4.1.
How can I fix it?</p>
