Does OpenJDK or Oracle JDK have a feature like "method trace" on IBM JDK?
Should I use AOP (for example, AspectJ)?

2OpenJDK has everything needed for such tracing. There are JVMTI MethodEntry/MethodExit events, `-XX:+DTraceMethodProbes` for tracing with DTrace/SystemTap, Instrumentation API to inject tracing calls into the bytecode (that's how AspectJ works). – apangin Oct 30 '18 at 07:33

If you are trying to debug a program, I would use a debugger. – Peter Lawrey Oct 30 '18 at 16:56

@PeterLawrey No. I want to know execution time per method in a way as easy as possible. – Kohei TAMURA Oct 31 '18 at 00:27
