Description

The script:

def execute() {
    for (def i = 0; i < 4; ++i) { println i }
}

execute()

works exactly as expected. However:

import groovy.transform.CompileStatic

@CompileStatic execute() {
    for (def i = 0; i < 4; ++i) { println i }
}

execute()

creates an infinite loop in which the value of i is always 0.
