Write documentation for working with Comet's spark-4.0 profile in IntelliJ

[andygrove]

What is the problem the feature request solves?

When switching from the default profile to the spark-4.0 profile (and the jdk-17) profile, I ran into various issues with building and running tests.

I plan on writing up some documentation on how to do this. Here are some brief notes.

• Close IntelliJ project
• Delete .idea folder
• make release PROFILES="-Pspark-4.0 -Pscala-2.13"
• open folder as project in IntelliJ
• select spark-4.0 and jdk-17 profiles (be sure to deselect the other profiles if needed)
• re-sync / re-import maven project
• build / rebuild
• run tests, adding the following JVM arguments (these are available in the pom.xml)

-XX:+IgnoreUnrecognizedVMOptions
      --add-opens=java.base/java.lang=ALL-UNNAMED
      --add-opens=java.base/java.lang.invoke=ALL-UNNAMED
      --add-opens=java.base/java.lang.reflect=ALL-UNNAMED
      --add-opens=java.base/java.io=ALL-UNNAMED
      --add-opens=java.base/java.net=ALL-UNNAMED
      --add-opens=java.base/java.nio=ALL-UNNAMED
      --add-opens=java.base/java.util=ALL-UNNAMED
      --add-opens=java.base/java.util.concurrent=ALL-UNNAMED
      --add-opens=java.base/java.util.concurrent.atomic=ALL-UNNAMED
      --add-opens=java.base/jdk.internal.ref=ALL-UNNAMED
      --add-opens=java.base/sun.nio.ch=ALL-UNNAMED
      --add-opens=java.base/sun.nio.cs=ALL-UNNAMED
      --add-opens=java.base/sun.security.action=ALL-UNNAMED
      --add-opens=java.base/sun.util.calendar=ALL-UNNAMED
      -Djdk.reflect.useDirectMethodHandle=false
