Cannot suppress JPanel constructor when extending class

[GoogleCodeExporter]

I have a class like this:

import javax.swing.JPanel;
import java.awt.LayoutManager;

final class MyPanel extends JPanel {

    MyPanel(final LayoutManager layoutManager) {
        super(layoutManager);
    }
}

I have a test like this:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

import javax.swing.JPanel;
import java.awt.BorderLayout;
import java.awt.LayoutManager;

@RunWith(PowerMockRunner.class)
@PrepareForTest(MyPanel.class)
public final class MyPanelTest {

    @Test
    public void test() {
        PowerMock.suppress(PowerMock.constructor(JPanel.class, LayoutManager.class));
        new MyPanel(new BorderLayout());
    }
}

I get the following exception:

org.powermock.reflect.exceptions.ConstructorNotFoundException: Failed to lookup 
constructor with parameter types [ org.powermock.core.IndicateReloadClass ] in

I expect the test to pass with no exception.

What version of the product are you using? On what operating system?

I am using PowerMock 1.4.10 with Java 1.6.0_17 on Windows 7 x64.

Try using Whitebox.newInstance(MyPanel.class) instead. The reason is probably 
because MyPanel cannot be bytecode manipulated correctly because it's a 
standard Java class.
