Michael Skells created LOGBACK-1509: --------------------------------------- Summary: TargetLengthBasedClassNameAbbreviator allocates lots of String Key: LOGBACK-1509 URL: https://jira.qos.ch/browse/LOGBACK-1509 Project: logback Issue Type: Improvement Components: logback-classic Environment:     Reporter: Michael Skells Assignee: Logback dev list In our internal application this account for 30% of all string allocation. It looks to me that the `TargetLengthBasedClassNameAbbreviator`, or probably all `Abbreviator` should cache the result for a class, rather than generate more memory pressure -- This message was sent by Atlassian JIRA (v7.3.1#73012)
