title: SonarQube analysis failed java.lang.OutOfMemoryError: Java heap space
body: <p>I am using SonarQube version 5.3 and using Jenkins version 1.651 to start the Sonar Scanner. I am also using the Sonar Java plugin version 3.11-build4121.</p>
  
  <p>There seems to be a problem the memory. From my debugging I found that a possible solution may be to increase the maximum Java Heap size by using the flag -Xmx in Jenkins. So I attempted this setup:</p>
  
  <pre><code>-Xss1024k -Xmx4096m -XX:MaxPermSize=256m
  </code></pre>
  
  <p>But without any success since it produces the following errors. </p>

  <p>I noticed this post: <a href="https://groups.google.com/forum/#!msg/sonarqube/gKdcwvvi4Kk/V0y3jVqXAwAJ" rel="nofollow">1</a> which experiences a similar problem but the problem seems to have been solves once the heap memory size was set to 4096 which it has not for me.</p>
  
  <p>Any suggestions on how I can solve this problem? </p>

  <p>The entire project is around 760mb in size and 1 million lines of code.</p>
