Java agent does not work with Java Flight Recorder

[charlesverdad]

I can't run pyroscope-java agent with the Java flight recorder (-XX:StartFlightRecording flag).

15:41:51 ❯ java -XX:-Inline -XX:StartFlightRecording -javaagent:pyroscope.jar Main
2022-01-24 15:41:58.002 INFO PyroscopeAgent We recommend specifying application name via env variable PYROSCOPE_APPLICATION_NAME

[1]    91159 illegal hardware instruction  java -XX:-Inline -XX:StartFlightRecording -javaagent:pyroscope.jar Main

Steps to reproduce

• Copy Main.java from the java example in the main repo
• Compile it and then run with -XX:StartFlightRecording flag

javac Main.java
java -XX:-Inline -XX:StartFlightRecording -javaagent:pyroscope.jar Main

Error:

[1]    91159 illegal hardware instruction  java -XX:-Inline -XX:StartFlightRecording -javaagent:pyroscope.jar Main

OS: MacOS 11.6.1 Big Sur (intel)

If I run it inside docker I get java_app_1 exited with code 139

Expected behaviour

From my understanding the java pyroscope agent uses async-profiler under the hood. And because async-profiler works even with Java flight recorder enabled, I expect pyroscope to work too.

Java app with flight recorder and without pyroscope:

15:47:18 ❯ java -XX:-Inline -XX:StartFlightRecording  Main
Started recording 1. No limit specified, using maxsize=250MB as default.

Use jcmd 92349 JFR.dump name=1 filename=FILEPATH to copy recording data to file.

Running async-profiler on the java process works even with flight recorder:

15:47:06 ❯ ./profiler.sh -e cpu,alloc,lock -f profile2.jfr 92349
Profiling for 60 seconds
Done

The async-profiler worked with flight recorder, so I was expecting pyroscope to work too.
