Description Antonin Nebuzelsky 2004-08-27 13:01:19 UTC 
Repeatedly redeploying web project leaves
o.n.m.web.api.webmodule.WebModule (and other
objects it refers to) in memory. See the
screenshots of OptimizeIt window attached below.

Steps to reproduce:
1) create or open web project
2) open project's jsp page
3) modify the jsp page
4) save and close the jsp page
5) run Redeploy Project in popup of the project
6) GO TO STEP 2)

Each cycle of the process leaves 7 instances of
WebModule class, held through 7 instances of
JspParserAccess$WM registered as listeners (see
the screenshot).
