Feel free to search, there’s many discussions on the topic. I don’t know why Bitronix did what they did - that certainly is giving them a monotonic clock, but ask yourself why didn’t they use nanoTime then? (hint: because it won’t work either). Anyway, I’m not saying that you shouldn’t change it to nanoTime.. just pointing out that neither is a gret fit ./ ( https://hibernate.atlassian.net/browse/HHH-13879#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-13879#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
