Spring JDBC throws an error which impacted my Spring related unit testing

Question

I am working on Spring Boot Rest Controller and everything is working fine including its unit testing.

When I added the Spring-jdbc(4.3.5.RELEASE) in my maven configuration, all my unit test classes are failing due to a null pointer exception. And if I remove it all my spring related unit testing classes are working fine again.

I have been using Spring so many years but this is the first time I have encountered this issue.

What is the root cause? I am using Spring boot 1.4.2.

Code:

@Test
public void verifyEmail() throws Exception {           
    mockServer.expect(requestTo("localhost:8080//api/v1/userEmails?email=test@test.com&catalogId=10051"))
        .andExpect(method(HttpMethod.GET))
        .andRespond(withSuccess("True", MediaType.APPLICATION_JSON));

    String s = acquisitionService.verifyEmail("test@test.com","10051");

    mockServer.verify();

    assertEquals("Assert Status", s, "True");                
}

Error Stack trace:

String s = xxxxxService.verifyEmail("test@test.com","10051"); — Shannon Riz Yabut, Jul 11 '17 at 19:55
The DI is working fine for the xxxxService that I have created but the verifyEmail method in it is throwing a Null pointer exception. — Shannon Riz Yabut, Jul 11 '17 at 20:01

@ShannonRizYabut, If I could make a suggestion, instead of adding this information in comments I think it would be better to edit your question with these details — Sean Carroll, Jul 11 '17 at 20:07
Thanks Sean Carrol. I just edited my question and added the one of the failing unit test classes and its stack trace. Take note that I haven't implemented anything related to spring JDBC yet, I just simply added the Spring JDBC library in the maven config and then it throws null pointers exception for all spring related unit test classes. — Shannon Riz Yabut, Jul 11 '17 at 20:16
It might be issues of dependency conflict. You can check in POM.xml in Dependency Hierarchy section. — Darshan, Jul 14 '17 at 03:06
