Description

Helper.groovy

@groovy.transform.CompileStatic
class Helper {
    void addToCollection(Collection coll, int index, val) {
        coll[index] = val
    }
}

Compiled with 2.1.1 the decompiled class looks something like this:

import groovy.lang.GroovyObject;
import groovy.lang.MetaClass;
import groovy.transform.TypeChecked.TypeCheckingInfo;
import java.util.Collection;

public class Helper
  implements GroovyObject
{
  public Helper()
  {
    Helper this;
    MetaClass localMetaClass = $getStaticMetaClass();
    this.metaClass = localMetaClass;
  }

  @TypeChecked.TypeCheckingInfo(inferredType="AAlDbGFzc05vZGUAAAFWAP////8=", version=1)
  public void addToCollection(Collection coll, int index, Object val)
  {
    Object localObject = val;
  }

  static
  {
    __$swapInit();
    long l1 = 0L;
    __timeStamp__239_neverHappen1367381386616 = l1;
    long l2 = 1367381386616L;
  }
}

The method doesn't really do anything.
