Errors interacting with other agents

In some cases we have had reports of Cinnamon used with other JVM agents causing instrumentation conflicts. For example, one user upgraded their New Relic agent and encountered an error from java.util.concurrent.CompletableFuture.cnmCallbackAdded. If you encounter something like this, with multiple agents, then the first suggestion is to change the ordering of the agents in your JVM args. Additionally, you can open a support case via the portal or support@lightbend.com so that we can look into it further - especially if you are able to provide a minimal reproducer.
