Problem when trying to start a measurement when using the Tanuki Software Wrapper

user5281936Oct 13 2014 — edited Oct 14 2014

Hello,

I am trying to run a test with the Java Flight Recorder, and I am getting this exception:

<< Could not start recording. Unexpected error occured when loading setting /apps/java/jdk1.7.0_55/jre/lib/jfr/default.jfc from JRE_HOME/lib/jfr. >>

Any suggestions as what can cause this error?

Thanks

I tested with other Java programs, and it is working well. It may be related to the way the JVM is started (with the wrapper)

This is an output of the wrapper log file:

--> Wrapper Started as Daemon

Launching a JVM...

Wrapper (Version 3.2.3) http://wrapper.tanukisoftware.org

......

This is an example of the wrapper/java configuration:

#********************************************************************

# Wrapper Properties

#********************************************************************

# Java Application

wrapper.java.command=/apps/java/jdk1.7.0_55/jre/bin/java

# Java Flight Recorder

wrapper.java.additional.26=-XX:+UnlockCommercialFeatures

wrapper.java.additional.27=-XX:+FlightRecorder

wrapper.java.additional.28=-XX:StartFlightRecording=duration=120s,filename=test-1.jfr,settings=/apps/java/jdk1.7.0_55/jre/lib/jfr/default.jfc

wrapper.java.additional.29=-XX:FlightRecorderOptions=loglevel=trace
