when the following JSP 2.0 TCK request was sent to the server
GET /jsp_coresyntx_script_el_web/ElNumberCoercionTest.jsp HTTP/1.0

Have attached the test.war file containing ElNumberCoercionTest.jsp.

hs_err_pid22095.log - JDK crash log when 1.5.0_03-b07 and -Xint were used
hs_err_pid22215.log - JDK crash log using 1.5.0_05-ea-b02

Here are the steps to reproduce the problem:
1. Install Web Server 7.0 (MS5 build)
   * cd /java/re/sjsws/7.0/promoted/MS5/latest/bundles/solaris
   * gunzip and untar sjsws-7.0_2006Q1-MS5-solaris-sparc.tar.gz in a temp directory
   * Run ./setup from that directory and follow the instructions to install WS7
     into a directory (e.g. /space/ws7)
     You don't have to be root to install WS7. You can install as your userid
2. Extract the attached test.war file into some directory (/space/test)
3. Edit the web server's config file - server.xml - and increase the stack size
   % cd /space/ws7/https-*/config
   % edit server.xml using your fav editor and change
      <stack-size>131072</stack-size>
    to
      <stack-size>231072</stack-size>
4. Add the web-app entry to server.xml
   Add the following XML snippet in server.xml after the </search-app> element
    <web-app>
        <enabled>true</enabled>
<uri>/jsp_coresyntx_script_el_web</uri>
<path>/space/test</path>
    </web-app>
5. Start the web server
   % cd /space/ws7/https-*/
   % bin/startserv
     You should see messages such as the following
[19/Jul/2005:15:22:51] info (22215): WEB0100: Loading web module in virtual server [test] at [/jsp_coresyntx_script_el_web]
[19/Jul/2005:15:22:54] info (22215): Starting Servlet Engine
[19/Jul/2005:15:22:59] info (22215): Missing application web.xml, using defaults only StandardEngine[com.sun.web].StandardHost[test].StandardContext[]
[19/Jul/2005:15:22:59] info (22215): HTTP3072: [LS http-listener-1] http://hogswart:1894 ready to accept requests
[19/Jul/2005:15:22:59] info (22215): CORE3274: successful server startup

6. Access the JSP from a browser by sending a request for /jsp_coresyntx_script_el_web/ElNumberCoercionTest.jsp

7. Watch the error log for a crash. WS7's error log is /space/ws7/https-*/logs/errors

Any JDK crash logs will be saved in the 'config' directory of the server instance i.e. /space/ws7/https-*/config

If you want to add more JVM options, you can do so by editing server.xml and adding the options to any of the existing <jvm-options> elements.

I tried -Xint, -Xss2048k but could still see the crash.
