Description
Steps to reproduce.
- Create a continuous JFR that contains virtual thread-related JDK attributes (example below). Please use profile.jfc within JDK 20 for a fresh recording,
<event name="jdk.VirtualThreadStart">
<setting name="enabled">true</setting>
<setting name="stackTrace">true</setting>
</event>
<event name="jdk.VirtualThreadEnd">
<setting name="enabled">true</setting>
</event>
<event name="jdk.VirtualThreadPinned">
<setting name="enabled">true</setting>
<setting name="stackTrace">true</setting>
<setting name="threshold">20 ms</setting>
</event>
<event name="jdk.VirtualThreadSubmitFailed">
<setting name="enabled">true</setting>
<setting name="stackTrace">true</setting>
</event>
- Dump the JFR directly from JMC, or try to open an already dumped JFR to the file system
- The direct dumping from JMC, or opening the JFR file in JMC fails with the following message
[2.544s][info][jfr,startup] Use jcmd 30940 JFR.dump name=JMC_Default filename=FILEPATH to copy recording data to file.
