[jira] [Commented] (LOG4J2-2724) SimpleMessage - message duplication (String and CharSequence fields)

["Remko Popma (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-2724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16976423#comment-16976423 ] 

Remko Popma commented on LOG4J2-2724:
-------------------------------------

From memory, The charSequence field is populated when the log(charSequence, ...) API is called. In any case, even if both fields are populated they would both reference the same memory so I cannot imagine this consuming significantly more memory. Do you have evidence to the contrary?

>             Project: Log4j 2
>          Issue Type: Bug
>          Components: API
>    Affects Versions: 2.12.1
>            Reporter: Dzmitry Anikechanka
>            Priority: Minor
>
> org.apache.logging.log4j.message.SimpleMessage class contains 2 fields:
> {code:java}
> private String message;
> private transient CharSequence charSequence; {code}
> These 2 fields contains the message that should be logged.
> So as the result the message is duplicated and it can cause significant payload on memory in case of logging large messages.
> Could you please fix it or explain why the message is duplicated?
> Thanks,
> Dzmitry
