If I use "-Djrebel.log=true" this does not happen (this option does not disappear). But that option (jrebel.log=true) is not available in their documentation. It's "rebel.log".
btw, when I clicked "Never publish automatically" the save button is enabled.
This has been verified by the ZT support team to be a bug in JRebel. Plz ignore. thx.
I just wanted to thank you for getting back to us. So few users do. Many file jira bugs or forum posts and don't post the resolution when they find it. So I'm very grateful for you getting back to us and letting you know you found the solution (or at least the cause of the problem).
