I just hit this same issue. Here's my full output:
Profiler Agent: JNI OnLoad Initializing...
Profiler Agent: JNI OnLoad Initialized successfully
Profiler Agent: Waiting for connection on port 5140 (Protocol version: 20)
Profiler Agent: Established connection with the tool
*** Profiler engine warning: Cannot use ClassLoader.findLoadedClass() and/or ClassLoader.findBootstrapClass() in ClassLoaderManager

Profiler Agent Error: GetCurrentThreadCpuTime failed with 73
Assertion failed: (res == JVMTI_ERROR_NONE), function Java_org_graalvm_visualvm_lib_jfluid_server_system_Timers_getThreadCPUTimeInNanos, file ../src-jdk15/Timers.c, line 108.

This is simple to reproduce in the https://github.com/FusionAuth/java-http project using the branch bpontarelli/virtual-threads
. Happy to provide build and run instructions if needed.
Describe the bug
Whenever I try to Profile the CPU for a program with virtual threads it fails with the following error:
The error code
73
corresponds to JVMTI_ERROR_UNSUPPORTED_OPERATION.The error seems to be triggered in
Timers.c
:Looking into the source code of jdk21 it seems that the function
GetCurrentThreadCpuTime
doesn't support virtual threads:To Reproduce
TriggerVisualVMProfileCrash.java
:Activate de CPU Profiler for the class
TriggerVisualVMProfileCrash
:Press
enter
in the console so the program continues execution.The program will crash
