Description

Consider the following Java class:

package b;

import java.util.concurrent.Callable;

public class B {
	private String name;

	public B(final String name) {
		this.name = name;
	}
	
  public void setCallable(final Callable<String> c) {
	  System.out.println(name + ": " + String.valueOf(c));
  }
}

and the following Groovy class:

@CompileStatic
class Test {

	static main(args) {
		def clos = { 'bar' } as Callable<String>
		B b1 = new B('b1')
		B b2 = new B('b2')
		b1.callable = b2.callable = clos
	}
}

Run Test class as a Groovy script: b1.callable is assigned null, instead of the clos closure. Remove the @CompileStatic in Test, re-run and... all goes right!
