MockFor and StubFor call unsupported method in ProxyGenerator for creation of instances of Abstract classes

      Description

      public abstract class MyNode {

      }

      @Test
      public void testCreateStubNode()

      { def stubNodeContext = new StubFor(MyNode) assertNotNull(stubNodeContext.proxyInstance()) }

      @Test
      public void testCreateStubNodeDelegate()

      { def stubNodeContext = new StubFor(MyNode) assertNotNull(stubNodeContext.proxyDelegateInstance()) }

      @Test
      public void testCreateMockNode()

      { def mockNodeContext = new MockFor(MyNode) assertNotNull(mockNodeContext.proxyInstance()) }

      @Test
      public void testCreateMockNodeDelegate()

      { def mockNodeContext = new MockFor(MyNode) assertNotNull(mockNodeContext.proxyDelegateInstance()) }

      In any case (and with a non-empty Abstract class such as import javax.media.j3d.Node) the result is:

      groovy.lang.MissingMethodException: No signature of method: groovy.util.ProxyGenerator.instantiateAggregateFromBaseClass() is applicable for argument types: (java.lang.Class, null) values: [class MyNode, null]

      Which appears to be absolutely true: the ProxyGenerator only has these 3 method signatures, none of which have the Class as the 1st argument (save the single parameter version)...

      instantiateAggregateFromBaseClass(Class)
      instantiateAggregateFromBaseClass(Map, Class)
      instantiateAggregateFromBaseClass(Closure, Class)
