title: Java 8 - Can not import java.util.Arrays
body: <p>After updating to Java 8, I (and a lot of other people) had problems with their eclipse. I resolved the path variable problem. Fine.</p>
  
  <p>So I have old projects in Eclipse. When I have the open, I delete the JRE 7 library and add 8. All the errors go away (from previously error-less code) except an import statement:</p>
  
  <pre><code>import java.util.Arrays;
  </code></pre>
  
  <p>I've seen the other questions on S.O. but they do not answer my problem (such as <a href="https://stackoverflow.com/questions/18621394/import-java-util-arrays-in-jdk8" title="this">this</a>, which just tells the OP he didn't have a semicolon). Besides it not resolving the source of the import, my code works! So what is it that could have changed?</p>
