Bug Report
Description of problem:
Generate one java operator through docs :https://github.com/operator-framework/java-operator-plugins/blob/main/docs/tutorial.md. The CR related resources can't be deleted when CR is deleted.
Version-Release number of selected component (if applicable):
operator-sdk version: "v1.20.0-ocp", commit: "4db4731ae75f2cccae951dd7ed98484662179c55", kubernetes version: "v1.24.1", go version: "go1.18.3", GOOS: "linux", GOARCH: "amd64"
How reproducible:
always
Steps to Reproduce:
1.generate one operator through https://github.com/operator-framework/java-operator-plugins/blob/main/docs/tutorial.md
The Reconciler logic:
https://github.com/operator-framework/java-operator-plugins/blob/main/testdata/quarkus/memcached-quarkus-operator/src/main/java/com/example/MemcachedReconciler.java
2.install the operator
$operator-sdk run bundle quay.io/olmqe/memcached-quarkus-bundle:v0.0.1-kaka
3.create CR
1)$oc create -f resources/memcached-sample.yaml
apiVersion: cache.example.com/v1
kind: Memcached
metadata:
name: memcached-sample
spec:
Add fields here
size: 1
2)$oc get pods

4.delete CR
1)$ oc delete Memcached memcached-sample
memcached.cache.example.com "memcached-sample" deleted
2)$ oc get pods
NAME READY STATUS RESTARTS AGE

Actual results:
Delete CR success but the related deployment still exists.
Expected results:
CR Memcached memcached-sample and related deployment are deleted success

What did you do?
Created operator and ran it using OLM. Creation and updating of Custom Resource is working but when I deleted CR it did not delete the created Pods.
What did you expect to see?
It should delete the Pods created by using the Custom resource.
What did you see instead? Under which circumstances?
Pods did not get deleted.

Possible Solution
The Cleaner class is not imported which will take care of the finalizers. Check with the Java operator SDK team.
