Pipeline is looping between self update and build

The issue is with the below code which I added in code build step to create a unit test report.

Map<String, String> reportGroupProps = Map.of(
                "files", "**/*.xml",
                "base-directory", "lambda/build/test-results/test/",
                "file-format", "JUNITXML"
        );
Map<String, ?> reports = Map.of(reportGroup.getReportGroupArn(), reportGroupProps);
Map<String, ?> reportsMap = Map.of("reports", reports);

It looks like cdk does Map.toString() somewhere in the code. Map.of() changes the order of keys while doing toString(), which result in cdk diff. This diff creates the pipeline to update, hence it is looping.

I tested with the below code, the hashmap and treemap is consitently giving the same order, whereas map.of() changes the order.

Map<String, String> mp = Map.of("k1", "v1", "k2", "V2");
System.out.println("mp = " + mp);

Map<String, String> hp = new HashMap<>();
hp.put("k1", "v1");
hp.put("k2", "v2");
System.out.println("hp = " + hp);

Map<String, String> smp = new TreeMap<>();
smp.put("k1", "v1");
smp.put("k2", "v2");
System.out.println("smp = " + smp);
