RFR: 7903908: JMH: Helpful message when benchmark builds are misconfigured

[Aleksey Shipilev]

When JMH benchmark project is misconfigured, the runner would print an unhelpful error like:


Exception in thread "main" java.lang.RuntimeException: ERROR: Unable to find the resource: /META-INF/BenchmarkList
at org.openjdk.jmh.runner.AbstractResourceReader.getReaders(AbstractResourceReader.java:98)
at org.openjdk.jmh.runner.BenchmarkList.find(BenchmarkList.java:124)
at org.openjdk.jmh.runner.Runner.internalRun(Runner.java:252)
at org.openjdk.jmh.runner.Runner.run(Runner.java:208)
at org.openjdk.jmh.Main.main(Main.java:71)


This is especially often when JDK 23 disabled annotation processors by default. We need to print more helpful message to guide users to resolution.
