Description

There is a regression due to GROOVY-7349. The following code will fail with a VerifyError:

@CompileStatic
private void foo(String[] arr) {
    for (String s in arr) {
        { -> println(s)}.call() // make s closure shared
    }
}

A workaround is to use an intermediate variable:

@CompileStatic
private void foo(String[] arr) {
    for (String s in arr) {
        def v = s;
        { -> println(v)}.call()
    }
}
