Code review comment: Nevermind, I see it just continued the trend from before. 

Code before review:
public static void main(Function<String, String> environmentVarGetter) throws Exception {
JvmInitializers.runOnStartup();
System.out.format("SDK Fn Harness started%n");
System.out.format("Harness ID %s%n", environmentVarGetter.apply(HARNESS_ID));
System.out.format(
"Logging location %s%n", environmentVarGetter.apply(LOGGING_API_SERVICE_DESCRIPTOR));
System.out.format(
"Control location %s%n", environmentVarGetter.apply(CONTROL_API_SERVICE_DESCRIPTOR));
System.out.format(
"Status location %s%n", environmentVarGetter.apply(STATUS_API_SERVICE_DESCRIPTOR));
String id = environmentVarGetter.apply(HARNESS_ID);
String pipelineOptionsJson = environmentVarGetter.apply(PIPELINE_OPTIONS);
try {
String pipelineOptionsPath = environmentVarGetter.apply(PIPELINE_OPTIONS_FILE);
System.out.format("Pipeline Options File %s%n", pipelineOptionsPath);
if (pipelineOptionsPath != null) {
Path filePath = Paths.get(pipelineOptionsPath);
if (Files.exists(filePath)) {
System.out.format(
"Pipeline Options File %s exists. Overriding existing options.%n",
pipelineOptionsPath);
pipelineOptionsJson = new String(Files.readAllBytes(filePath), StandardCharsets.UTF_8);
}
}
} catch (Exception e) {
System.out.format("Problem loading pipeline options from file: %s%n", e.getMessage());
}
System.out.format("Pipeline options %s%n", pipelineOptionsJson);
PipelineOptions options = PipelineOptionsTranslation.fromJson(pipelineOptionsJson);
Endpoints.ApiServiceDescriptor loggingApiServiceDescriptor =
getApiServiceDescriptor(environmentVarGetter.apply(LOGGING_API_SERVICE_DESCRIPTOR));
Endpoints.ApiServiceDescriptor controlApiServiceDescriptor =
