synchronized code in DefaultActionInvocation

[Musachy Barroso]

This code in DefaultActionInvocation.createResult:

ActionConfig config = proxy.getConfig();
Map<String, ResultConfig> results = config.getResults();

ResultConfig resultConfig = null;

 synchronized (config) {
            try {
                resultConfig = results.get(resultCode);
            } catch (NullPointerException e) {
                // swallow
            }
            if (resultConfig == null) {
                // If no result is found for the given resultCode, try
to get a wildcard '*' match.
                resultConfig = results.get("*");
            }
        }

I can't see why wee need to synchronize that block...any ideas?
