NPE in REST endpoint generated by hibernate-orm-rest-data-panache in Gradle project

[rsynek]

Describe the bug

This is a regression likely introduced by https://github.com/quarkusio/quarkus/commit/827f778c9ab71478b19ce230ac5a5265bfdba592 (confirmed locally by building and using the snapshot).

In a Gradle project that uses the quarkus-hibernate-orm-rest-data-panache, a generated REST resource, that is supposed to add a new entity, throws an NPE: Cannot invoke "io.quarkus.hal.HalService.getSelfLink(Object)" because the return value of "io.quarkus.arc.InstanceHandle.get()" is null (see the attached complete stacktrace)

• the same project based on maven works
• downgrading the Quarkus Gradle plugin to 2.13.0.Final also works (the regression was introduced in 2.13.1.Final)

Expected behavior

Pass the test in the linked reproducer.

Actual behavior

NPE during test execution.

Thanks for reporting this @rsynek, I think the issue will be resolved with #28440

[punkratz312]

same over here: thanks for report and fix

Closing as a duplicate of https://github.com/quarkusio/quarkus/issues/28440. The workaround for now is to add io.quarkus:quarkus-resteasy-reactive-kotlin as a dependency explicitly.

Caused by: java.lang.NullPointerException: Cannot invoke "io.quarkus.hal.HalService.getSelfLink(Object)" because the return value of "io.quarkus.arc.InstanceHandle.get()" is null

the dependency does not fix the issue plus this seems to be an fishy workaround, we dont need that module before why should we add it then?

[punkratz312]

dont seems to be an general issue, the other project is more complex, panache and more maybe thats some hint:
