EclipseLink NullPointerException Cannot read field "index" because "key" is null #28078

njr-11 · 2024-04-03T16:14:25Z

Describe the bug

The JPQL query SELECT o FROM Account o WHERE (o.accountId=?1) fails when supplied with an AccountId that is an embeddable id for the entity.

EclipseLink converts this to SQL: SELECT BALANCE, BANKNAME, CHECKING, OWNER, ACCOUNTNUM, ROUTINGNUM FROM WLPAccount WHERE ((ACCOUNTNUM = ?) AND (ROUTINGNUM = ?))
which looks fine, but it gets an error processing the result: NullPointerException: Cannot read field "index" because "key" is null.

KyleAure · 2024-07-25T16:32:33Z

FYI @njr-11 @Riva-Tholoor-Philip

I was unable to recreate. I also un-commented and ran the original test and it works from Jakarta Data as well.
Perhaps this bug was fixed in one of the beta versions of EclipseLink we have upgraded too?

My recreation attempt: KyleAure@1483d53

…hat it is fixed

Oh, I didn't realize it worked via Jakarta Data now, too. Then yes, EclipseLink must have fixed it already. I just tried it locally as well and given that worked, and I requested a build to confirm that its working there as well. I set up the PR to automatically close this issue.

…low more of test to run

njr-11 · 2024-07-26T16:41:32Z

When I attempted to re-enable this under #29200 I discovered that it's an intermittent issue that appears to happen when the test testEmbeddedId, which uses the same entity, runs first.

Riva-Tholoor-Philip · 2024-07-30T05:25:17Z

Thanks @njr-11

KyleAure · 2024-07-30T19:08:26Z

Reopening issue. The PR accidentally automatically closed this, it is still an issue that needs to be resolved.
