Dear all,
I have one question on how to run Java benchmark.
I built jar files by executing the following command " on an x86_64
machine. Then, based on [1], I tried to execute a Java benchmark program.
However, I got an exception. I can find the BenchmarkList file, but it is
not included in the jar file. What do I do mistakes?
