JMC shows less number of events when its opened for analysis , whereas if the the JFR file is printed as XML file using jfr tool , then it will have more events listed.
Number of Events Shown in XML (65086)
Number of Events Shown in JMC (65084)
Anomalies Noticed
| Event Type (as in XML format) | Count | Issue Description |
| jdk.JavaExceptionThrow | 145 | JMC Shows only 143 Events for this |
| jdk.JavaMonitorEnter | 1 | Shown As Java Monitor Blocked |
Steps to reproduce
- Download the attached JFR (your_recording.jfr) and open it in JMC 8.0.0
- Go to Event Browser and Select all events , and see the total number of events in properties (Ref JMC.png)
- Convert jfr tp XML using jfr tool (JDK11_HOME\bin\jfr print --xml your_recording.jfr > your_recording.xml)
- List the number of events ( grep -c "<event " your_recording.xml )
- Compare the events listed on both , and there's a mismatch
