http://bugzilla.qos.ch/show_bug.cgi?id=117 Summary: Synchronization of SimpleDateFormat object in DateConverter Product: logback-classic Version: unspecified Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Other AssignedTo: logback-dev@qos.ch ReportedBy: anders@hammar.net 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. -- Configure bugmail: http://bugzilla.qos.ch/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
