A FileAlreadyExistsException happens when downloading custom code artifacts in rare cases.

Issue

• A java.nio.file.FileAlreadyExistsException happens when configured using custom code artifacts in the spec.dependencies.artifacts field of Infinispan CR in rare cases. So the RHDG pod cannot start and the result, the pod restarts repeatedly.

  Infinispan CR:

  apiVersion: infinispan.org/v1
  kind: Infinispan
  metadata:
   name: infinispan
  spec:
   replicas: 2
   dependencies:
     artifacts:  <<== HERE
