Subject [jira] [Commented] (JOHNZON-161) JohnzonCDIExtension might create a mem leak
Date Wed, 22 Apr 2020 11:44:00 GMT

    [ https://issues.apache.org/jira/browse/JOHNZON-161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17089594#comment-17089594

Romain Manni-Bucau commented on JOHNZON-161:
--------------------------------------------

[~skay] great ):.

 

Just a side note for future readers: it is not "closed automatically", just let to the garbage
collector (so some advanced usages of the underlying mapper - addCloseable - or other features
can still leak). It is unlikely but can happen and I don't want readers assume there is any
magic there.

> We use Json-B quite heavily and I experienced that there are tons of elements in org.apache.johnzon.jsonb.cdi.JohnzonCdiExtension#jsonbs.
> Way too much for my gut feeling.
> The reason is that we do not use JsonBuilder as autocloseable is that it is not required
by the spec.
>  
> There is also not much documentation for JohnzonCdiExtension, so I can only guess that
it is for cleanly shutting down unused JsonbBuilder instances when the app stops.
> We should probably only store WeakReferences.
>  
> I think the safest
