locally failing failover test

hi!

Right now I am looking into why the itests/failover fails locally.
Might be something stupid I broke, not sure.

Anyway, while looking at it I found the following in the log

This happens because the JavaAgent gets attached to the bootstrap =
classpath. So that very jar which winds up getting attached needs to =
have jakarta.persistence available. It seems that's not the case.
Likely only a test setup issue as we would have seen this in production =
otherwise.
