epsilon and G1 seem not to work with JFR in NI #8993

Open buuuuuuug opened 1 month ago

buuuuuuug commented 1 month ago

Describe the issue epsilon GC and G1 GC seems cannot work properly with JFR enabled in NI mode by throwing an error msg of Pool jdk.types.GCName must contain at least one element or Pool jdk.types.GCCause must contain at least one element sometimes on application start. while serial GC works just fine. is there anything that i possibly miss?

Steps to reproduce the issue Please include both build steps as well as run steps

  1. [git clone https://github.com/buuuuuuug/jfr-vth-pin.git]
  2. [gradle nativeCompile]
  3. [modify build.gradle file by buildArgs.add('--gc=G1') or buildArgs.add('--gc=sepsilon').]
  4. [./build/native/nativeCompile/jfr-vth-pin -XX:StartFlightRecording="filename=recording.jfr,settings=continue+vth.jfc"]

Describe GraalVM and your environment:

I believe G1 and epsilon are not supported in JFR based on https://github.com/oracle/graal/issues/8978 @roberttoyonaga can you please confirm?

Yes that's right. But using JFR with any of the other GCs should not throw exceptions. I'll look more into this.
