Low coverage rate of the fix for 8050804

Need to implement new tests to cover new code.

+ 985 | if (!jdkinternals.isEmpty()) {
- 986 | log.println();
- 987 | log.format("%-40s %s%n", "JDK Internal API", "Suggested Replacement");
- 988 | log.format("%-40s %s%n", "----------------", "---------------------");
- 989 | for (Map.Entry<String,String> e : jdkinternals.entrySet()) {
- 990 | log.format("%-40s %s%n", e.getKey(), e.getValue());
- 991 | }

Not covered code is marked with '-'.
