>             Project: Jackrabbit Oak
>          Issue Type: Bug
>          Components: segment-azure
>    Affects Versions: 1.72.0

> I came across a NPE in the AzureRepositoryLock refreshing logic, which terminates this thread and renders the repository unusable, so eventually the service needs to be terminated.
> Fixing this NPE would be highly appreciated.

> I see this bug already reported in https://github.com/Azure/azure-sdk-for-java/issues/38646, and the recommendation is to update the Azure library to a more recent one.
> I have found OAK-11267 for it, but I am not sure about the progress there, so I recommend to add here a check to avoid this NPE until the SDK version was upgraded
