Sebb updated LANG-367:
----------------------
Attachment: FastDateFormat.patch
Make HashMaps final
> FastDateFormat thread safety
> ----------------------------
>
> Key: LANG-367
> URL: https://issues.apache.org/jira/browse/LANG-367
> Project: Commons Lang
> Issue Type: Bug
> Reporter: Sebb
> Attachments: FastDateFormat.patch
>
>
> FastDateFormat has several static HashMaps. These are currently not final, so
> there is no guarantee that they will be visible to all threads.
> Patch to follow.
> Also, as far as I can make out, the class shares SimpleDateFormat instances
> between threads.
> It does not document why this is OK.
> I'm guessing that it assumes that instances of the SimpleDateFormat class are
> thread-safe provided that they have the same attributes, but this is not
> documented. If this is the case, it's not clear that it is a valid assumption.
