Thank you for reviewing it.
If you are using OracleJDK, it won't have any output. OracleJDK doesn't suffer from crash. I guess It suppress events unconditionally.
For JDK8u, "-XX:+EnableTracing -version" will dump some events. It won't crash if it has this patch http://hg.openjdk.java.net/jdk8u/jdk8u-dev/hotspot/rev/80ee2541504e
The attachment is the output.

I don't see any output produced with just "-XX:+EnableTracing -version". ??
