Description

In the following script, the empty range is apparently treated as a slice of size 1:

testMethod()

@groovy.transform.CompileStatic
def testMethod() {
    def list = ["1", "2", "3", "4"]

    assert list[0..<0] == []
    println list
}

If you remove the annotation, the assertion passes.
