Secret rotation failing after LoginTokenExpiredEvent

[benallaerts]

Hey,

Problem
I'm trying to use spring-vault in my application with dynamic secret rotation for the database.

All secret renewals and rotations are working fine until the login token expires. On token expiration all secrets are correctly rotated, but on the next renewal the following exception is thrown

org.springframework.vault.VaultException: Cannot renew lease
	at org.springframework.vault.core.lease.SecretLeaseContainer.doRenewLease(SecretLeaseContainer.java:766)

The void restartSecrets() method in the SecretLeaseContainer seems to cancel and clear all stored renewals on login token expiration, but the newly created LeaseRenewalScheduler used to rotate the secret is never added to the stored renewals. This seem to cause the above exception when the next rotation is attempted.

Setup

framework	version
java	21
spring	6.1.6
spring-boot	3.2.5
spring-vault	3.1.1
Hashicorp Vault	1.16.3

Authentication is done using APPROLE credentials

That's fixed now.

Since this is a big Problem with long living services, is there an ETA for Release 3.1.2 ?
