[jira] [Created] (WW-3751) Memory leak using jsp tags on an app
deployed on glassfish
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
Issue Type: Bug
Components: Other
Affects Versions: 2.3.1.1, 2.3.1, 2.2.3, 2.2.1.1, 2.2.1
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
Ram: 6.00 GB
GlassFish Server Open Source Edition 3.1.1 (build 12).
It also happens in production environment with different hardware configuration running Linux
Reporter: Marco Malavolta
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

----------------------------------------
Ciao Marco,
is this related with WW-3702 in someway?
No problem for me. We could put the issue on hold at the moment and seeing what happens on the Glassfish side.

Ciao Maurizio,
This issue is not directly related to https://issues.apache.org/jira/browse/WW-3702.
I fell into two issues, the first (and not the worst in terms of burned memory) was the one reported in WW-3702. It has been solved by glassfish 3.1 release, probably by some fixes on Weld.
If you have a chance to take a look at the sample app i've posted on glassfish's jira, you will notice that no plugins are involved. I've only linked the latest struts2-core libraries.
Thank you for your utra fast willingness, which I appreciate a lot.

-------------------------------------
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?

Marco Malavolta commented on WW-3751:
-------------------------------------
The trick does not work.
After setting jasper to use pool, some other classes than JspWriterImpl hangs on memory and produces the same result.
Finally I've switched to tomcat, I will reintroduce ejbs once tomee will be released on a final version.
Only one more thing.
I followed this instruction http://docs.jboss.org/weld/reference/1.0.0/en-US/html/environments.html in order to add cdi support to tomcat.
The strut2 cdi plugin does not work because it searches the beanManager with those keys: "java:comp/BeanManager" and "java:app/BeanManager".
Tomcat only allows to bind entries to java:comp/env, so the BeanManager is available at java:comp/env/BeanManager.
If you want me to open an issue for the plugin I'll do.

----------------------------------------
Ciao Marco,
I have just tried the example you provided and I can confirm the presence of the issue on Glassfish (apropos, thank you for the accurate and clear test case).
At the same time, I have to say you that the error does not occur under Tomcat neither under Jetty (which would make me think that this is a Glassfish issue).
Under both the application servers, the tenured gen memory has never exceeded 20MB in size (though Jetty is much slower than Tomcat).
I'm trying to understand what really differs from Glassfish and I'll ping you back.

[jira] [Commented] (WW-3751) Memory leak using jsp tags on an app
deployed on glassfish

----------------------------------------
Ciao Marco,
finally I found the [culprit|http://java.net/jira/browse/GLASSFISH-8601].
What really differs between Tomcat and Glassfish is the jsp implementation. In fact, according with the Glassfish docs the pool is disabled by default, whereas Tomcat [enables it by default|http://tomcat.apache.org/tomcat-6.0-doc/config/systemprops.html].
Although this is not within my sphere of competence, I guess that if you set the system property "org.apache.jasper.runtime.JspFactoryImpl.USE_POOL" to true it should be work at the same way of Tomcat.
I will try to find out what is holding the JspFactoryImpl/JspWriterImpl

----------------------------------------
Another thing that I can confirm is that Tomcat reuses the same instances of PageContextImpl and consequently PageContextImpl.
Glassfish doesn't.

--------------------------------------
{quote}
The strut2 cdi plugin does not work because it searches the beanManager with those keys: "java:comp/BeanManager" and "java:app/BeanManager".
Tomcat only allows to bind entries to java:comp/env, so the BeanManager is available at java:comp/env/BeanManager.

Please open an separate Issue for this Problem.
