title: Eclipse loads but gives an error "initializing java tooling"
body: <p>I have been running eclipse properly.  After it loads I get:
  "Initializing Java Tooling".
  Incompatible magic value 0 in class file org/eclipse/jdt/internal/core/search/BasicSearchEngine</p>
  
  <p>I have been looking, and what I have found is Eclipse hanging initializing java tooling</p>
  
  <p>I have set JAVA_HOME and -vm in eclipse.ini  </p>
  
  <p>Still, no success.</p>
  
  <p>Any ideas would be appreciated</p>

  (Stack Overflow won't let me post this as an answer cause I am of ill repute.)</p>
  
  <p>Never mind.</p>
  
  <p>It may be important to have the answer to what I did so that people that have the same issue does not have to go through the hoops I went.</p>
  
  <p>First, I went to the Help/About Eclipse/Installation Details. In the Installation History, with using compare and revert, I started reverting what I had installed (Compare and Revert are pretty cool BTW.) I finally detected which was the latest stable version, and the installation that broke it all</p>
  
  <p>Spring Source at <a href="http://dist.springsource.com/release/TOOLS/update/e3.7" rel="nofollow">http://dist.springsource.com/release/TOOLS/update/e3.7</a></p>
  
  <p>Initially I selected some extra components that sounded cool, but the second time around I pretty much went for the required, plus support for AOP, Web Tools, and Flex and WebServices. Other than that I ignored all the rest of the stuff. That worked.</p>
  
  <p>I had selected before (one of the ones that killed it, do not exactly which one), in addition to what I left installed: Spring Mylyn Integration Spring Tool Suite AWS Integration Spring Tool Suite Maven Support Eclipse Weaving Source</p>
  
  <p>I also had the "Mylyn Builds Connector: Jenkins/Hudson integration", which had worked for me in the past. I still suspect that it was one of the Spring components.</p>
  
  <p>I hope this helps</p>
