Eduardo Quintanilla commented on WW-5009:
-----------------------------------------

I mean using a variable instead of a field. Sorry for the confusion. https://github.com/lalo-mx/struts/commit/ed29e3f4ed841ef13559c02da1c8dca9b68fb0a7

> EmptyStackException in JSON plugin due to concurrency
> Note: The issue was found in an app that was upgraded from version 2.3.34 
> Logs: [^logs.txt]
> I created a sample application that should help reproducing the error.
> [^struts-json-example-master.zip]
> The error happened opening the app (localhost/struts-json-example) in 4 different browsers
/ sessions.
> As a workaround I have overridden the JSONInterceptor so a new instance of JSONUtil is
used with every request and the issue is not happening anymore. I suppose there is a performance
cost with that change but for now it works.
