Hello all,

when trying to start the weblogic jvm with the appmon agent I get this error.

2019-10-08 18:16:48 [00000002] info [native] Average transformation time for 1333 classes/modules was 0ms - maximum set to 60ms

[jfr][ERROR][0,989] Redefine class failed with 71

Error when initializing JFR. JFR will be deactivated.

java.lang.Exception: Could not instrument Throwable!

at oracle.jrockit.jfr.VMJFR.instrument(VMJFR.java:410)

at oracle.jrockit.jfr.JFR.init(JFR.java:109)

Error occurred during initialization of VM

Failed to start tracing backend.



How can I eliminate this error and start the weblogic?


thanks in advanced.

Did you try turning off JFR and trying again? Basically JFR and AppMon are both trying to instrument your JVM and there appears to be a conflict.

What version of AppMon are you using?

As a last resort, you could tell Dynatrace to ignore the class(es) that's having trouble.

Let's first start with the above steps and go from there.


turning off JFR works !!

thank you
