NPE on getEnclosingMethod()

[Dennis Gesker]

Hello OpenJDK list...

I do hope this is the correct list for user questions. I'm getting a NULL
when calling:

this.getClass().getEnclosingMethod()

I was going to file a bug but I'm not yet a contributor and hope to get
login credentials soon. Any chance an existing member could take a look at
my unit test below? And, if verified and not duplicate file a bug report on
my behalf?

Thanks,
Dennis

Using:

openjdk version "11.0.5-ea" 2019-10-15
OpenJDK Runtime Environment (build 11.0.5-ea+10-post-Ubuntu-0ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.5-ea+10-post-Ubuntu-0ubuntu1, mixed
mode, sharing)

The following test compiles (-Xlint:all -Werror) but throws and NPE on
execution:

package test;

import static org.junit.Assert.assertTrue;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.junit.jupiter.api.Test;

public class CheckForNullEnclosingMethod {
private Logger logger = Logger.getLogger(this.getClass().getSimpleName());

@Test
public void iSeemToBeLost() {

if (this.getClass().getEnclosingMethod() == null) {
logger.logp(Level.SEVERE, this.getClass().getName(),
this.getClass().getEnclosingMethod().getName(),
"What method am I in?");
assertTrue(this.getClass().getEnclosingMethod() == null);
assertTrue(this.getClass().getEnclosingMethod().getName() == null);
return;
}

logger.logp(Level.INFO, this.getClass().getName(),
this.getClass().getEnclosingMethod().getName(),
"No worries, I'm not lost");
assertTrue(this.getClass().getEnclosingMethod() != null);
assertTrue(this.getClass().getEnclosingMethod().getName() != null);

}
}
