Regression

• The issue is a regression

Expected behavior

should have provisions to conditionaly add agents during startup

Actual behavior

not defined

How to Reproduce?

appears that JAVA_OPTS_APPEND does not honor -javaagent

say wile starting up i want to do
-javaagent:codeguru-profiler-java-agent-standalone-1.2.3.jar="profilingGroupName:keycloak,heapSummaryEnabled:true"
not sure how to get this done without modifying kc.sh

Anything else?

Moved this to a discussion.

JAVA_OPTS_APPEND is already recognized as an ENV variable, if I do something like:

JAVA_OPTS_APPEND=-javaagent:codeguru-profiler-java-agent-standalone-1.2.3.jar="profilingGroupName:keycloak,heapSummaryEnabled:true" ./kc.sh start-dev

I can see on the console that the property is being used:

Appending additional Java properties to JAVA_OPTS

And my vm fails to start because I don't actually have that codeguru-profiler-java-agent-standalone-1.2.3.jar

Why do you expect it to be handled as a system property?

well, i was able to acheive it iwht java_opts_append something like this

    - name: "AWS_CODEGURU_PROFILER_HEAP_SUMMARY_ENABLED"
      value: "true"        
    - name: "AWS_CODEGURU_PROFILER_GROUP_NAME"
      value: "keycloak-perf-test"        
    - name: "JAVA_OPTS_APPEND"
      value: '-javaagent:"/path/to/myprofilerdirectory/profiler-java-agent.jar"'
