Subject [jira] [Commented] (LANG-909) Thread-safe wrapper for SimpleDateFormat
Date Fri, 24 Jan 2014 19:52:38 GMT

    [ https://issues.apache.org/jira/browse/LANG-909?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13881365#comment-13881365

Dmitry Katsubo commented on LANG-909:
-------------------------------------

[~britter]: As you can read from {{FastDateParser}} JavaDoc, it supports into Gregorian calendars.
For other calendars it creates {{SimpleDateFormat}}. In such "unpopular" scenarios {{ThreadSafeSimpleDateFormat}}
is still beneficial. However added value is not big, so maybe one can copy code to his project
directly from this issue after googling a while.

> {{SimpleDateFormat}} implementation in JDK is known to be [not thread-safe|http://stackoverflow.com/questions/6840803/simpledateformat-thread-safety].
The attached helper class solves the problem by holding a separate instance of {{SimpleDateFormat}}
per thread.
