Throw StackOverflowError when child method invoke twice parent method using PowerMock Mockito

[shuxiang520]

I tried to use PowerMock with Mockito to mock one test case but it throw StackOverflowError exception.

I am using 1.6.3 version as below:
<powermock.version>1.6.3</powermock.version>
...
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-easymock</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>

The case is as below, I want to test print method in Child, and mock Parent method. Which child method will invoke parent method twice.

class Parent {
public void print() {
System.out.println("print Parent");
}
}

class Child extends Parent {
public void print() {
super.print(); // invoke parent method first time
System.out.println("print Child");
super.print(); // invoke parent method second time
}
}

Then I use below test class to test:
@RunWith(PowerMockRunner.class)
@PrepareForTest({
Parent.class
})
public class Test {
@Test
public void print() {
PowerMockito.suppress(MemberMatcher.method(Parent.class));
Child child = PowerMockito.spy(new Child());
child.print();
}
}

When I run this test case, it throw StackOverflowError exception as below:

I created a test to verify your issue, but I cannot reproduce it. You may find my code here: https://github.com/jayway/powermock/pull/705/files

By the way, I'm also wondering, why you use both easymock and mockito API modules?
