StringIndexOutOfBoundsException for "/*" <url-pattern> of <jsp-property-group>

[glassfishrobot]

Hi Glassfish developers!
Specifying URL pattern "/*" for in web.xml:

<jsp-config>
    <jsp-property-group>
      <url-pattern>/*</url-pattern>
      <include-prelude>/WEB-INF/theme/header.jsp</include-prelude>
      <include-coda>/WEB-INF/theme/footer.jsp</include-coda>
    </jsp-property-group>
  </jsp-config>

causes Glassfish (org.apache.jasper) to crash with HTTP 500

Originally I found this bug when using Jetty but Jetty just include Glassfish's JSP implementation therefore reporting here. Related Jetty bugzilla issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=401531

Testing shows this isn't an issue with the upstream Apache Tomcat JSP implementation in any current version. I'm leaving this open as it may be an issue in Glassfish but I suspect it is Jetty specific given https://bugs.eclipse.org/bugs/show_bug.cgi?id=401531#c4
