Benchmarks fail with "No enum constant ...ObjectType.zBQYA0GAwBAbAUGA"

[Jo Durchholz]

Hi all,

Running things with Maven from the command line, so the Eclipse setup in
eclipse/ from the Github Repo does not work for me, I get
java.lang.IllegalArgumentException: No enum constant
com.esotericsoftware.kryo.benchmarks.FieldSerializerBenchmark.BenchmarkState.ObjectType.zBQYA0GAwBAbAUGA

The zBQYA0GAwBAbAUGA comes from a JMH parameter
(is says objectType = zBQYA0GAwBAbAUGA).

There's a single .class file for an ObjectType class,

benchmarks/target/classes/com/esotericsoftware/kryo/benchmarks/FieldSerializerBenchmark$BenchmarkState$ObjectType.class
but the enum contains no "zBQYA0GAwBAbAUGA", just "sample" and "media",
so this indeed cannot work.

What's wrong?

Regards,
Jo

P.S.: Here's the output from run.sh:

The part from "# Run progress" repeats, a lot.

Hi Jo,

I've always run the benchmarks using IntelliJ by starting the main class in KryoBenchmarks.

The bundled jars in the lib folder are probably out of date.

Can you please create an issue on Github?

Best,

Thomas

I guess I should try that, too.

Oh. Somebody please remove them then :-)

I was surprised to find bundled libs, anyway.

I was going to suggest removing manual instructions since just using
Maven is fine, but then I recalled that some corporate environments
block Maven downloads but allow browser downloads.
So manual instructions are probably needed, just don't include the
libraries but tell users where to download the stuff. The instructions
could be created from a `mvn dependency` output, possibly as a shell script.

Done:
https://github.com/EsotericSoftware/kryo/issues/1065

I didn't add the zBQYA0GAwBAbAUGA observation, as it might be a
follow-up error from the classpath problem.

Jo

This worked.
I had to change Settings though:
Build, Execution, Deployment
-> Compiler
-> Java Compiler
-> Use --release option for cross-compilation (Java 9 or later)
needs to be OFF, otherwise IntelliJ will believe that the sun.misc
package does not exist.
Maybe my Java setup plays a role, I had set the JDK to Temurin 11.
It's a bit weird, I'm seeing JDK 11 and JDK 17 directories so I was
expecting module system issues have been dealt with, but ah well.

It's a bit unfortunate since this setting affects all projects on my
disk, but since my plans for hacking on Kryo are limited, I guess I'll
stick with that unless somebody has a better idea.
Haven't tried JDK 8 yet. Maybe I can switch the setting back.
It would have been nice to benchmark with more than one JDK though.

Regards,
Jo
