Compiler error for aspectj static method in base class

[mamuninfo]

Hi
I have a base class entity with two drive class for single table. In base class there are some static finder method that is related to the database. So I created a finder aspect for that. It works fine from eclipse but when I run it from roo or maven then I got compiler error-

Base class-

@RooEntity(versionField = "", table = "T_P")
@Inheritance(strategy=InheritanceType.SINGLE_TABLE);
@DiscriminatorColumn(name="CLASS_TYPE_DISCRIMINATOR", discriminatorType=DiscriminatorType.INTEGER);
@DiscriminatorValue("0");
public class Purchase{

}

Finder aspect for purchase with generic static method
Compiler error code

aspect Purchase_Finder{
public static <U extends Purchase> Long Purchase.countPurchases(Class<U> type) {

}

Sub class-

@Entity
@DiscriminatorValue(value="1");
public ContentPurchase extend Purchase{
}

Test case for content purchase

@ContextConfiguration(locations = "classpath:/META-INF/spring/applicationContext.xml")
@RunWith(SpringJUnit4ClassRunner.class)
@Transactional
public class ContentPurchaseTest {
       @Test
	public void countContentTest(){
		Long contentCount = ContentPurchase .countPurchases(ContentPurchase .class);
		Assert.assertNotNull(contentCount );
		Assert.assertTrue(contentCount >0);
	}

}

When I run this test case from eclipse then it works fine. But when I run it through roo or maven I get the following error-

ContentPurchaseTest .java: The method countPurchases(Class<ContentPurchase >) is ambiguous for the type ContentPurchase

One more things- If I move those static method from aspectj to java class then it works fine both eclipse and roo.
Working code -

public class Purchase{
//moving code from asject
public static <U extends Purchase> Long countPurchases(Class<U> type) {
}

aspect Purchase_Finder{

}

I have also other method that are common for sub class are working fine from eclipse project but neither roo nor maven.
