initializationError in Eclipse when #PrepareForTest is at method but at class - eclipse

Question

Small example, using jUnit 4.11, Mockito 2.6.3, PowerMock 1.7.0RC4:
public class TheClass {
public static int giveMeNumber() {
return 70;
}
public static int giveMeThatNumber(int it) {
return it;
}
}
and
import org.junit.Test;
import org.junit.runner.*;
import org.mockito.*;
import org.powermock.api.mockito.*;
import org.powermock.core.classloader.annotations.*;
import org.powermock.modules.junit4.PowerMockRunner;
#RunWith(PowerMockRunner.class)
// #PrepareForTest(TheClass.class)
public class TheTestClass {
#Test
#PrepareForTest(TheClass.class)
public void test1() {
PowerMockito.mockStatic(TheClass.class);
Mockito.when(TheClass.giveMeNumber()).thenReturn(13);
System.out.println(TheClass.giveMeNumber());
}
#Test
#PrepareForTest(TheClass.class)
public void test2() {
PowerMockito.mockStatic(TheClass.class);
Mockito.when(TheClass.giveMeThatNumber(25)).thenReturn(50);
System.out.println(TheClass.giveMeThatNumber(25));
}
#Test
public void test3() {
System.out.println("Hey, I do not want a #Prepare...d class!");
}
}

When I run those tests in eclipse (right click at class name, Run as..., JUnit test), they pass (not actually checking anything, I know :-) ). When I run them alone (right click at method name, Run as..., JUnit test), they fail with an initializationError [Runner: JUnit 4] (0,000s) without any trace.
Strangely, when I remove the #PrepareForTest(TheClass.class) from the method signatures and uncomment it in the class signature, all three run fine both together and alone.
But now look: test3() says it does not want a "prepared" TheClass. What I thought was correct, is to move the #PrepareForTest(TheClass.class) from the class signature to the signatures of the methods that need it (test1() and test2()), like it was before but failed.
What am I doing wrong?
