Notes

Create a JDK Flight Recording
- (see java options at https://docs.oracle.com/en/java/javase/14/docs/specs/man/java.html and scroll down to -XX:StartFlightRecording)
- For the programmatic program:
  - Build the distribution with ./gradlew programmatic:installDist
  - Set the JRE options with export PROGRAMMATIC_OPTS="-XX:StartFlightRecording,dumponexit=true"
  - Run the program with programmatic/build/install/programmatic/bin/programmatic
- For the standalone program:
  - Build the distribution with ./gradlew standalone:installDist
  - Set the JRE options with export STANDALONE_OPTS="-XX:StartFlightRecording,dumponexit=true"
  - Run the program with standalone/build/install/standalone/bin/standalone
- After the program exits, the .jfr file will be captured. Visualize it using Mission Control https://github.com/openjdk/jmc
- Clone Mission Control and build it
- You must run it with a JDK 8 (and it must be installed at /Library/Java/JavaVirtualMachines... for some reason. I couldn't get an SDKMAN installed Java to work)
  - E.g. JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/ target/products/org.openjdk.jmc/macosx/cocoa/x86_64/JDK\ Mission\ Control.app/Contents/MacOS/jmc -vm $JAVA_HOME/bin
Can we run WireMock on Graal? If Jetty can run on Graal, then WireMock should be pretty easy to run on Graal. See an example for running Jetty on Graal at javalin/javalin#286
