Mocking System.nanoTime() cause StackOverflowError #317
Description
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());
}
