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}",
      ),
    )
