    Description

      The following code works well dynamically, properly type checks, but fails static compilation:

      @groovy.transform.CompileStatic test() {
          def versionRanges = [['1.7', 11]]
          versionRanges.collect { versionRange -> versionRange[1].collect { versionRange[0] } }.flatten()
      }
      
      test()
      
      Exception thrown
      
      BUG! exception in phase 'class generation' in source unit 'ConsoleScript23' At line 3 column 45
      On receiver: versionRange with message: getAt and arguments: 1
      This method should not have been called. Please try to create a simple example reproducing this error and filea bug report at http://jira.codehaus.org/browse/GROOVY
      

      Although it's reported on the first versionRange[1], it's actually seems related to the second call (versionRange[0]). If you remove that second call, all is fine.
