Date.toString was improved by eliminating static GregorianCalendar and SimpleDateFormat instances. However, it calls TimeZone.getDisplayName to get an abbreviation of a time zone. In the getDisplayName implementation, it uses a HashMap with synchronization. The HashMap should be replaced with a ConcurrentHashMap to improve concurrency.
This defect will be fixed in: 5.0.0 SR? . The use of ConcurrentHashMap has imporoved the concurrency and the hang that was seen before is avoided . . To obtain the fix: Install build 20110924 or later
