> {{JdbcCachedMessageIdRepository.remove}} (and {{clear}}) removes the key from
> its cache before and after the delete. When the repository is used in a
> transaction of the caller on the same DataSource (or JTA), the delete joins
> that transaction and is only committed later: for example a direct {{remove}}
> or {{clear}} in a transaction, or the idempotent consumer removing the key of
> a failure that a dead letter channel handled inside an enclosing transaction
> that commits. Until then, another thread still sees the row: its {{add}} of
> the key finds the row, returns false (a duplicate) and caches the key. When
> the caller's transaction commits, the row is gone but the key stays in the
> cache, so every later {{add}} of that key is rejected as a duplicate without
> a row, until the cache is reloaded (a restart).
> Expected: once the remove is committed, the key is not in the cache.
> Possible fix: also remove the key from the cache in the {{afterCommit}} of
> the caller's transaction (a transaction synchronization, as {{add}} uses
> since CAMEL-26770 to cache a key only after its row is committed).
> Found in the review of CAMEL-26770 (apache/camel#29533), from reading the
> code; confirmed with a test (H2: remove in an open transaction on one thread,
> add on another, then commit).
> _Filed with Claude Code on behalf of allthingssecurity._
