While I think it is good to avoid the NullPointerException
, I think the crux of this problem is you are somehow getting a null ObjectPostProcessor
. Can you please put together a sample that demonstrates this happening?
The test context may be completely wrong configured, still the following test throws the NPE in my project:
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;
@ContextConfiguration(classes={WebSecurityConfiguration.class})
@RunWith(SpringRunner.class)
@WebAppConfiguration
public class SpringBugTest {
@Test
public void thisWillNotRun() throws Exception {
System.out.println("Foooooooooooooooooooooooooo");
}
}
The stacktrace:

Summary
org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.objectObjectPostProcessor
field is marked as not required. When it is not present, the methodspringSecurityFilterChain
throws aNullPointerException
Actual Behavior
If there are
webSecurityConfigurers
, and there is noobjectObjectPostProcessor
org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.springSecurityFilterChain() throws NPE in line number 99. (Version 5.1.5-RELEASE).The method looks like this currently:
Expected Behavior
I think the method should look like this:
Configuration
I am not currently sure why this
ObjectPostProcessor
is null by me. I will add details here, as soon as I figure it out. Still the NPE is something wrong, if the objectPostProcessor is not required.Version
5.1.5-RELEASE. The code is still wrong in master, as far as I see
Sample
I think no sample is required, since the code is simple to understand.
