----------------------------------------
Summary: Add UnresolvedAddressException to the list of transient
exceptions that can prevent lease renewal Add UnresolvedAddressException to the
list of transient exceptions that can prevent the lease renewal
Key: OAK-12112
URL: https://issues.apache.org/jira/browse/OAK-12112
Project: Jackrabbit Oak
Issue Type: Bug
Components: segment-azure
Affects Versions: 1.88.0
Reporter: Miroslav Smiljanic
Assignee: Miroslav Smiljanic
Fix For: 1.90.0
When the Azure lease renewal times out on the client side (reactor
IllegalStateException wrapping TimeoutException), the current exception
handling treats it as a fatal error and triggers shutdown, even though this is
a transient condition that should be retried. The exception handling in
refreshLease() should be updated to recognize timeout exceptions (similar to
BlobStorageException with OPERATION_TIMED_OUT) and continue the retry loop
instead of invoking the shutdown hook.
