Subject [jira] [Commented] (LOG4J2-1348) Add an AutoCloseable ThreadContext class: CloseableThreadContext
Date Tue, 05 Apr 2016 15:04:25 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-1348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15226415#comment-15226415

Greg Thomas commented on LOG4J2-1348:

The static method can't return `this` - but there's no reason why `put(...)` / `push(...)`
couldn't be instance methods as well as static methods. Something like

public static put(String key, String value) {
    return new CloseableThreadContext().put(key, value);

public CloseableThreadContext put(String key, String value) {
    return this;

However, this still requires new object creation, hence requiring garbage collection.

>            Assignee: Gary Gregory
>            Priority: Minor

> The log4j2 API provides a ThreadContext - https://logging.apache.org/log4j/2.x/manual/thread-context.html
-  that allows items to be added to a stack or a map for logging, and then subsequently removed
once they are no longer required.
> This sounds like an ideal candidate for a AutoCloseable implementation so that items
are removed automatically and no longer left around littering the stack/map.
