            Description

            In the org.icefaces.impl.util.Util class, we provide a static DateFormat for formatting and parsing dates for HTTP headers:

                public static final DateFormat HTTP_DATE =
                        new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz", Locale.ENGLISH);

            This utility is used throughout our code (components, ACE, framework). However, according to the JavaDoc for DateFormat:

            "Date formats are not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally."

            We should change our technique to provide thread-safe acquisition and use of the formatter.
