      Description

      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
