Hi devs,
I just wanted to know why the flashlight-agent.jar is no longer an OSGi
bundle, nor a HK2 archive, as opposed to 3.1 release?
I see that it moved from .../modules/ to .../lib/monitor/ but that path
does not seem to be referenced anywhere.
How's that supposed to work?
I ask because I'm getting this:
WARNING: Error while getting Instrumentation object from ProbeAgentmain
java.lang.ClassNotFoundException:
org.glassfish.flashlight.agent.ProbeAgentMain
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)
Two days ago it used to work and as I'm currently implementing a new
monitoring module it really blocks me here.
Thanx for any pointer,
Ancoron
P.S.: Full exception stacktrace (repeating for each probe provider
registration):
