Description

Spreading a list inside brackets causes a SpreadExpression should not be visited here during class generation. (The business instance of this is trying to use a list of URL patterns for Spring antMatchers.)

@CompileStatic
class Bug {
    public static final List<String> A = ['a1', 'a2']

    static void varargs(String... strings) {
        println Arrays.toString(strings)
    }

    public static void main(String... args) {
        varargs([
            *A
        ] as String[])
    }
}
