Description

Consider the following:

package p;
public class C extends java.util.HashMap {
  public    void setFoo(Object x) {}
  protected void setBar(Object x) {}
            void setBaz(Object x) {}
  private   void setBoo(Object x) {}
}

@groovy.transform.CompileStatic
void test(p.C p_c) {
  p_c.foo = null // works
  p_c.bar = null // SC: Method setBar is protected in p.C
  p_c.baz = null // IllegalAccessError
  p_c.boo = null // SC: Cannot call private method p.C#setBoo of class ...
}

Prior to GROOVY-11319, each of the non-public references produced error "Cannot access method setBxx(java.lang.Object) from class: p.C" – error improved by GROOVY-11223.
