===Project specific Java version ===

  * Basically, Eclipse is retarded and defaults every project to Java 1.5
  * We want Java 1.6 :|

So, go to Window -> Preferences -> Java -> Compiler 
  * Click 'Configure project specific settings
  * Select your project
  * Enable and Change Java version to 1.6
