hi @pierre @tungleduyxyz

The latest version of Kaui writes duplicate logs:

It happened somewhere between 3.0.9 and 3.0.11 and seems like https://github.com/killbill/killbill-admin-ui-standalone/pull/80 pull request is the only relevant one.

Do you have any ideas how to fix it? Thanks!

Thanks @yegortokmakov . Let me check it and respond to you ASAP.

Hi @yegortokmakov, It seems the root cause is here: https://github.com/killbill/killbill-admin-ui-standalone/pull/85 As I explained in the description, we had an issue with jruby-rack current version, so I had to build a custom JAR file(while waiting for the jruby-rack next release). That could be a reason for additional logs.
