java.lang.NoClassDefFoundError: com/hazelcast/com/fasterxml/jackson/core/JsonFactory

[vladykin]

Describe the bug Attempted to bump Hazelcast dependency version in our Quarkus 3.2-based app from 5.2.2 to 5.3.4. Started getting NoClassDefFoundError: com/hazelcast/com/fasterxml/jackson/core/JsonFactory in tests annotated with @QuarkusTest.

quarkus-hazelcast-client 4.0.0 refers to this class, but apparently it's not there in the latest Hazelcast.

Unfortunately, this happens in the quarkus deployment, so not much a mere user can do here ... It builds (and tests) fine with the following patch:

So maybe a fix could be made available soon(ish)?

[vladykin]

Thank you for the fix! Where will the new release of quarkus-hazelcast-client be available?

[rkraneis]

When can we expect a release with this fix? We are unable to use newer versions of Hazelcast Client without it unless we build quarkus-hazelcast-client from source ...
