Proposal: Replace lines (in DefaultComparator.compareValues(...))
if ((expectedValue == null && actualValue != null) || (expectedValue != null && actualValue == null)) {
result.fail(prefix, expectedValue, actualValue);
}
to
if (expectedValue == null && actualValue != null) {
result.unexpected(prefix, actualValue);
}
if (expectedValue != null && actualValue == null) {
result.missing(prefix, expectedValue);
