[ http://jira.qos.ch/browse/LBCLASSIC-36?page=com.atlassian.jira.plugin.system... ] Joern Huxhorn commented on LBCLASSIC-36: ---------------------------------------- This was just a side-effect of trying to get logback to compile using "mvn clean install". I'll take another look at DateFormatPerftest. My suggestion above is still standing (I know, we just had a comment race-condition ;)): how about the interface?

Synchronization of SimpleDateFormat object in DateConverter -----------------------------------------------------------

Key: LBCLASSIC-36 URL: http://jira.qos.ch/browse/LBCLASSIC-36 Project: logback-classic Issue Type: Bug Components: Other Affects Versions: unspecified Environment: Operating System: All Platform: All Reporter: Anders Hammar Assignee: Ceki Gulcu Attachments: DateConverter_patch.java, DateFormatPerfTest.java, dateformattest.zip

According to the API documentation of SimpleDateFormat, date formats are not synchronized and it is recommended to create separate format instances for each thread. However, a possibly simpler (mer efficient) solution would be to synchronize on the SimpleDateFormat object in the convert() method to prevent two threads to access it concurrently.
