title: Java 7 && IntelliJ
body: <p>I installed openjdk 1.7.0 and set it up in IntelliJ 10.5 </p>
  
  <p>When I compile (anything) I get the error "Fatal Error: Unable to find package java.lang in classpath or bootclasspath".</p>
  
  <p>I looked at this question:
  <a href="https://stackoverflow.com/questions/3049433/intellij-gives-fatal-error-unable-to-find-package-java-lang-in-classpath-or-boot">IntelliJ gives Fatal Error: Unable to find package java.lang in classpath or bootclasspath</a> but all jar files inside the lib directory are already added.</p>
