Jukka Zitting commented on JCR-3775: ------------------------------------ Actually there are common enough cases where non-GMT time zones are used in timestamps, so I added the originally described map in revision 1590132. > Avoid lock contention in ISO8601.parse() > ---------------------------------------- > > Key: JCR-3775 > URL: https://issues.apache.org/jira/browse/JCR-3775 > Project: Jackrabbit Content Repository > Issue Type: Improvement > Components: jackrabbit-jcr-commons > Reporter: Jukka Zitting > Assignee: Jukka Zitting > Fix For: 2.8 > > > The ISO8601.parse() method calls the synchronized TimeZone.getTimeZone() > method, which causes lock contention in concurrent code that frequently > parses ISO8601 strings. > To avoid the synchronization, we could use a static flyweight map of all > known time zones, and only fall back to the getTimeZone() method if some > unknown time zone is encountered. -- This message was sent by Atlassian JIRA (v6.2#6252)
