Marco Malavolta commented on WW-3751:
-------------------------------------
Glassfish's team closed the issue with this explanation:
"An instance of JspWriterImpl (and its associated response buffer) is created
for every request. It should be released at the end of the request. If that is
not the case, then someone else is holding on to the page or the request, but
this is not the problem with JspWriterImpl per se."
Can you investigate?
> Memory leak using jsp tags on an app deployed on glassfish

> Key: WW-3751
> URL: https://issues.apache.org/jira/browse/WW-3751
> Project: Struts 2

> Environment: Windows 7 Professional (Microsoft Windows version 6.1
> Build 7601:Service Pack 1) 64 bit
> Processor: Intel Core i5 CPU 650 @ 3.20GHz 3.33 Ghz

> I have some webapps based on Struts 2 framework.
> I use JSP tags, even sometimes with nested Struts 2 tag (FreeMarker).
> Every time you call with a single jsp jsp tags JspWriterImp a new instance is
> created with more or less the contents of the tag (instead of reusing the
> same object stored in memory.
> This causes a loss of memory, because these objects are located in the old
> generation heap 'til the web application is restarted
> After a few days / weeks depending on the traffic that you need to restart
> because of irresponsiveness.
> I also created a Jira issue on GlassFish
> (http://java.net/jira/browse/GLASSFISH-18316), where I posted a screenshot
> and a sample application to reproduce the problem.
> Basically I'm not sure if it's a struts problem or a problem of glass fish.
> Perhaps the second hypothesis is more likely
> Feel free to close it if you feel that the problem is solely related to
> Glassfish
