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.
