title: How does one build the java JRE from source (src.zip in JDK)?
body: <p>Surprisingly enough I couldn't find the answer to this question.</p>
  
  <p>I am trying to rebuild the java JRE from source. I obtain the java JRE source by extracting the src.zip file in the JDK.</p>
  
  <p>After making any changes I need to make to the JRE, how do I compile the new source back into .java files (after which I can compress it into the rt.jar file).</p>
  
  <p>Thanks.</p>
