Concurrent formatters
by Diego Belfer 04 Jul '12

04 Jul '12

Hello, I was thinking of working on trying to convert the code of some of the formatters DecimalFormatter, SimpleDateFormatter, etc to allow concurrent calls to the format and parse methods. I know it has been discussed many times in the forums and I understand they were not initially designed for that, but it does not seem very difficult at first glance to attempt to make this enhancement. What do you think? Have you already tried to accomplish this and found some blocking issues? Do you think this change would make the API documentation confusing ? Best, Diego Belfer [muralx]

Hi Stuart, As requested - attached are 2 patch files, one covering util, the other text. I'm aware some fixes did go in recently, so if these patches are out of date and need re-spinning, then please let me know. Cheers, Martijn (on behalf of Adopt OpenJDK)
