title: increase IntelliJ java heap size
body: <p>after a lot of research I could not get a result. I'm new to IntelliJ IDEA, I use 11.1.2 version. I work with 3 modules (3 eclipse projects) and in each of them I setted <strong>Preferences -> Compiler -> Java Compiler</strong> with the following values:</p>
  
  <p><strong>Maximum heap size (MB):</strong> 512</p>
  
  <p><strong>Additional command line parameters:</strong></p>
  
  <p>-target
  1.6
  -XX:MaxPermSize=512M
  -Xms256m
  -Xmx512m
  -XX:PermSize=512m</p>
  
  <p><strong>And also configured Maven runner's VM Options as the following:</strong></p>
  
  <p>-XX:PermSize=1024m
  -XX:MaxPermSize=512m
  -Dfile.encoding=UTF-8
  -Duser.language=en</p>
  
  <p>with skip tests checked...</p>
  
  <p>I also changed <strong>Applications -> IntelliJ IDEA 12 -> Contents -> Info.plist</strong>:</p>
  
  <pre class="lang-xml prettyprint-override"><code>      &lt;key&gt;VMOptions&lt;/key&gt;
        &lt;string&gt;-ea -Xverify:none -Xbootclasspath/a:../lib/boot.jar&lt;/string&gt;
  
        &lt;key&gt;VMOptions.i386&lt;/key&gt;
        &lt;string&gt;-Xms256m -Xmx512m -XX:MaxPermSize=512m -XX:ReservedCodeCacheSize=128m&lt;/string&gt;
  
        &lt;key&gt;VMOptions.x86_64&lt;/key&gt;
        &lt;string&gt;-Xms256m -Xmx512m -XX:MaxPermSize=512m -XX:ReservedCodeCacheSize=128m -XX:+UseCompressedOops&lt;/string&gt;
  
        &lt;key&gt;WorkingDirectory&lt;/key&gt;
  </code></pre>
  
  <p>But after doing these changes IntelliJ shows me 200-250 MB of heap space allocated on the bottom right... What is wrong?</p>
