Environment

• CA APM 10.7 SP3 Agent
• Docker/Openshift/Kubernetes containers
• Agent configuration is done through Dockerfile and scripts

Cause

• Standard On-premise APM Java Agent Does NOT Support OpenJDK 11.
   

Resolution

• After few test cases, SaaS Agent works instead of on-premise Agent.
