RFR: CODETOOLS-7902853: JMH: Fix lint and deprecation warnings

[Niels Basjes]

In my projects I always use -Werror as the compiler flag as one of the means to get a high standard for code quality.
In this project https://github.com/nielsbasjes/yauaa I have a module that does the benchmarks.
When I update the JMH from 1.26 to 1.28 my build fails with 
[WARNING] COMPILATION WARNING : 
[INFO] -------------------------------------------------------------
[WARNING] /home/nbasjes/workspace/Prive/yauaa_/benchmarks/target/generated-sources/annotations/nl/basjes/parse/useragent/benchmarks/jmh_generated/AnalyzerBenchmarks_android6Chrome46_jmhTest.java:[324,67] redundant cast to long

and at the end it fails
[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] /home/nbasjes/workspace/Prive/yauaa_/benchmarks/target/generated-sources/annotations/nl/basjes/parse/useragent/benchmarks/jmh_generated/AnalyzerBenchmarks_android6Chrome46_jmhTest.java: warnings found and -Werror specified
[INFO] 1 error

Turns out this problem is caused by a change in code generated by JMH.

This pull request fixes this problem.
