           Summary: permanently reloading tagfile classes without changes to
                    the tagfile
           Product: Tomcat 5
           Version: 5.0.28
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: [EMAIL PROTECTED]
                CC: [EMAIL PROTECTED]


Scenario:

- jsp with a tag in it (tagfile, no taglib)
- activate "reloading" in web.xml
- clean work directory
- start tomcat
- load jsp

Tomcat generates/compiles/load the jsp and the tagfile classes. After
"checkInterval" seconds the background compile thread "JspRuntimeContext[\*]"
loads the tagfile classes (and only them) again and again. This produces a lot
of work for the garbage collector. (permanently class unloading of tagfile 
classes)

A Breakpoint in the method loadTagFile() in JspServletWrapper.java will show
this. Perhaps the reload flag must be set to false after loading the TagFile?

JspServletWrapper.java:
...

if(reload) {
   tagHandlerClass = ctxt.load();
   reload = false;  //perhaps, this solves the problem but i am not shure
}

...

After restarting the server the problem is not present because no
JspServletWrapper is instantiated for the tagfile an therefore the backround
compile task does not check the tagfile.
