Hi @garydgregory
Thank you for your time.
I removed Java 17 dependencies. Now everything works agains Java 8.
Also it's possible to run benchmarks from command line - exactly the same as
described in the official JMH doc.
Please find run instructions and example results here:
1.
https://github.com/HubertWo/apache-commons-lang-jmh/tree/main/string-joiner
2.
https://github.com/HubertWo/apache-commons-lang-jmh/tree/main/string-builder
I have also added GitHub Actions which run both benchmarks agains Java 8.
Logs from GitHub run:
```
StringJoinerBenchmark.stringJoinerPrimitiveInt thrpt 25 7963210.479
± 188742.938 ops/s
StringBuilderBenchmark.stringBuilderPrimitiveInt thrpt 25 21906622.479
± 950041.487 ops/s
```
1. GitHub build logs for StringJoiner benchmark:

2. GitHub build logs for StringBuilder benchmark:

> Please look at the sources in JDK, where
> java.lang.AbstractStringBuilder#append(boolean b)
> In short, for basic types, should not convert them to String, but use
> StringBuilder directly, will bring far better performance.
> BUT I just foundout that you did not bring this issue, this issue is already
> in commons-lang before your pr.
> So I will not stop you from merging this in, but still I will find time to
> refactor the whole join serial functions later.
