USDT java guide

[sebastiaoamaro]

Hi everyone, I was following the guide in [1], however, when attaching the usdt it fails with the error:

libbpf: usdt: no USDT notes section (.note.stapsdt) found in '/usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so'

Which I believe to be caused by not having dtrace enabled in the JVM, however, I can not find any guide/tutorial to enabling it.
Sorry for the unrelated question to eBPF, but did you enable anything to run java USDT? or use a specific java version?

Thanks in advance.
