and there are no missing null checks.

## Decision

Use "NullAway" in JSpecify mode to check for null-related errors in Java code.

Consider improper uses of `null` detected by NullAway a compilation error (not a warning, and not a separate CI job to test).

Do not suppress NullAway errors without a justification.

    // not needed when compiling with recent JDKs, e.g. 17
    options.compilerArgs.add("-Xlint:-requires-transitive-automatic")

    // Patch the compileKotlinJvm output classes into the compilation so exporting packages works correctly.
    options.compilerArgs.addAll(
      listOf(
        "--patch-module",
        "$moduleName=${compileKotlinTask.destinationDirectory.get().asFile}",
      ),
    )

When submitting code, please make every effort to follow existing conventions
and style in order to keep the code as readable as possible. Please also make
sure your code compiles by running `./gradlew check`. Checkstyle failures
during compilation indicate errors in your style and can be viewed in the
`checkstyle-result.xml` file.
