Mocking java internals with powermockrunner doesn't work in version 1.5

What steps will reproduce the problem?

This test will reproduce the problem:

import static org.powermock.api.mockito.PowerMockito.mock;

import javax.swing.*;

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

@RunWith(PowerMockRunner.class)
@PrepareForTest(JOptionPane.class)
public class PowerMockTest {
    @Test
    public void powermockTest() {
        mock(JTextArea.class);
    }
}

The test will fail as long as @PreprareForTest is present, no matter what class 
is being prepared.

The output is:

java.lang.LinkageError: loader constraint violation in interface itable 
initialization: when resolving method 
"javax.swing.text.JTextComponent$1.setDropLocation(Ljavax/swing/text/JTextCompon
