title: Kettle / Pentaho Data Integration not usable: very slow to start up and hangs on right click
body: <p>For all practical purposes, I cannot work with Kettle / Data Integration, although it is half of my new job. Does anyone have any insights?</p>
  <h3>Issue:</h3>
  <p>Kettle is very slow to launch, and immediately hangs and needs to be Force Quit when I right click on anything in the left side panel.</p>
  <p>That is the main issue, as there are some things you can only do by right clicking on the object you want in the view panel. But I believe there is also a configuration issue. For example, when I try to create a new database connection after creating a new transformation (both from the File menu), I get this error:<br/>
  “org.pentaho.ui.xul.XulException: java.lang.reflect.InvocationTargetException”</p>
  <h3>My config:</h3>
  <p>Mac OSX 10.12.6 (Sierra)<br/>
  Kettle, also known as Pentaho Data Integration, version 7.1.0</p>
  <h3>What I already attempted:</h3>
  <ul>
  <li><p>Uninstall and reinstall Kettle in 2 ways:<br/>
  o From the installer package on this website (which redirects to <a href="https://sourceforge.net/projects/pentaho/files/Data%20Integration/7.1/pdi-ce-7.1.0.0-12.zip/download" rel="nofollow noreferrer">https://sourceforge.net/projects/pentaho/files/Data%20Integration/7.1/pdi-ce-7.1.0.0-12.zip/download</a>) <br/>
  Uninstall: move Data Integration folder to Trash, as well as all files and folders containing “Kettle&quot;, and then Empty Trash <br/>
  o From Homebrew in the Terminal, using: <code>brew install kettle</code> <br/>
  This way installs version 6 <br/>
  Uninstall: <code>brew uninstall --force kettle</code></p>
  </li>
  <li><p>Close all apps in use, hard reboot my computer, kill memory intensive processes in Activity Monitor</p>
  </li>
  <li><p><code>Sudo purge</code></p>
  </li>
  </ul>
  <h3>Notes:</h3>
  <p>Kettle takes over 1 GB of memory right away after being started. <br/>
  Here is how I launch it, in Terminal, not by clicking on the .app item, because that doesn't work: <br/></p>
  <ul>
  <li>When installed from installer dmg package : <code>/Applications/data-integration/Data\ Integration.app/Contents/MacOS/JavaApplicationStub</code> <br/></li>
  <li>When installed from homebrew: <code>spoon.sh</code></li>
  </ul>
