Mocking System.nanoTime() cause StackOverflowError

[hkalina]

Affected JMockit version: 1.26 (example works correctly with 1.22 and 1.24)

Mocking of System.nanoTime() fails because using this method in URLClassLoader - mocking of time cause StackOverflowError during classloading. (Mocking of other System methods works ok.)

The same problem occure in version 1.24 if I omit @RunWith(JMockit.class) annotation.

@RunWith(JMockit.class)
public class MyTest {
    @Test
    public void test() {
        System.out.println(System.nanoTime());
        new MockUp<System>() {
            @Mock
            public long nanoTime(){
                return 1234;
            }
        };
        System.out.println(System.nanoTime());
    }
}
