MockUp of class extending Throwable throws NoClassDefFoundError

[ogray58]

Version
JMockit: 1.33
Java: 8

Description
If you create a Mock up of a class which extends Throwable, and Mock out printStackTrace(), as shown in the example code below, a call to the printStackTrace() on an instance of the mocked class will result in the following error: java.lang.NoClassDefFoundError: package/Class$MyThrowable

This error does not does not occur if:

• Throwable is used in the MockUp instead of MyThrowable
• The printStackTrace() method isn't mocked, but the MockUp is still created
• There is an an override of printStackTrace in MyThrowable

Code to Reproduce

@Test
public void test()
{
	new MockUp<MyThrowable>() {
		@Mock
		void printStackTrace() {}
	};

	new MyThrowable().printStackTrace();
}

static class MyThrowable extends Throwable {}
