title: rJava Cannot add to classpath
body: <p>When I attempt to use .jaddClassPath() or .jinit() to modify my classpath, it does not seem to have any effect on it.
  Here's what I have so far</p>
  
  <pre><code>&gt;&gt;classpath
  /Users/..../someFolder/
  &gt;&gt;.jinit(classpath)
  [1] 0
  &gt;&gt;print(.jclassPath())
  [1] "/Library/Frameworks/R.framework/Versions/3.1/Resources/library/rJava/java"
  </code></pre>
  
  <p>Also, I've tried this.</p>
  
  <pre><code>&gt;&gt;.jaddClassPath(classpath)
  &gt;&gt;print(.jclassPath())
  [1] "/Library/Frameworks/R.framework/Versions/3.1/Resources/library/rJava/java"
  </code></pre>
  
  <p>I'm running 
  rJava - 0.9.6
  R - 3.1.3
  OSX Yosemite</p>
