Description

Try compiling the following code using Groovy 3.0.9:

import groovy.transform.CompileDynamic
import groovy.transform.CompileStatic

@CompileStatic
class MyConstructorBug {
    @CompileDynamic
    MyConstructorBug() {
        StringReader reader = new StringReader("abc")
    }
}

It'll fail with the following exception:

java.lang.ArrayIndexOutOfBoundsException: size==0
