Subject [jira] [Commented] (LANG-909) Thread-safe wrapper for SimpleDateFormat
Date Mon, 13 Jan 2014 22:37:56 GMT

    [ https://issues.apache.org/jira/browse/LANG-909?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13870077#comment-13870077
] 

Charles Honton commented on LANG-909:
-------------------------------------

FastDateFormat was designed to be thread safe.  The thread safe wrapper came in slightly after
FastDateFormat was completed, and before FastDateFormat was released.   There was at one point
a unit test that proved SimpleDateFormat failed multi-thread safety, while FastDateFormat
passed.

> {{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.
