Partial layout debugging in JMockit

Question

Using JMockit 0.999.4 and JDK6, is it possible to debug a partially mocking class?

Consider the following test:

@Test
public void testClass() {
    SampleClass cls = new SampleClass();

    System.out.println(cls.getStaticInt());
    cls.setVal(25);
    System.out.println(cls.getVal());
}

static class SampleClass {
    static int staticInt = 5;
    private int val;

    {
        staticInt = 10;
    }

    public int getStaticInt() {
        System.out.println("Returning static int and adding a line for debugging");
        return staticInt; 
    }

    public void setVal(int num) {
        System.out.println("Setting val and adding a line for debugging");
        this.val = num;
    }

    public int getVal() {
        System.out.println("Returning val and adding a line for debugging");
        return this.val;
    }
}

Placing a breakpoint on each of the sysout lines in SampleClass and debugging "Step Over" in Eclipse will introduce the SampleClass methods.

Consider the following, which will not allow the static initializer to set staticInt to 10.

@Test
public void testClass(@Mocked(methods = "$clinit") SampleClass cls) {       

    System.out.println(cls.getStaticInt());
    cls.setVal(25);
    System.out.println(cls.getVal());
}

static class SampleClass {
    static int staticInt = 5;
    private int val;

    {
        staticInt = 10;
    }

    public int getStaticInt() {
        System.out.println("Returning static int and adding a line for debugging");
        return staticInt; 
    }

    public void setVal(int num) {
        System.out.println("Setting val and adding a line for debugging");
        this.val = num;
    }

    public int getVal() {
        System.out.println("Returning val and adding a line for debugging");
        return this.val;
    }
}

However, this code will not debug methods in SampleClass.

Yes, I tried the -javaagent property.
