Hello Pedro,

This is only a Warning message that you can safely ignore.
This is coming from a third-party jar whose maintainers are already aware of the message
The path also suggests that the xstream- is actually a dependency for your Findbugs plugin.
Therefore uninstalling the Findbugs plugin would be a workaround solution to get rid of the Warning message



Hi Eric

Thank you so much! Appreciated.
We also noticed a considerable increase in compute resource utilization. What used to work fairly well for us in 8.2-DevEdition, no longer worked on 8.4-DevEdition.
Used to work 8.2: request 1Gi / Limit: 2Gi (we had considerable number of restarts)
Required in 8.4: request 2Gi / Limit: 3Gi (not single restart)

nothing changed on our side other than upgrade itself. did not see any documentation stating that potential compute resource footprint would be impacted (more allocation). are we alone or this is known?

Thanks /Pedro
