The JSP which runs on JBoss 4.0.4 does not run on JBoss 4.0.5.

I got the following error :

2007-06-08 06:37:02,278 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/infinity-beta].[action]] Servlet.service() for servlet action threw exception

Snippet of the java code created for the JSP by JBoss :

private boolean _jspx_meth_tiles_get_6(javax.servlet.jsp.tagext.JspTag _jspx_th_c_otherwise_2, PageContext _jspx_page_context)
throws Throwable {
PageContext pageContext = _jspx_page_context;
JspWriter out = _jspx_page_context.getOut();
// tiles:get
org.apache.struts.taglib.tiles.GetTag _jspx_th_tiles_get_6 = (org.apache.struts.taglib.tiles.GetTag) _jspx_tagPool_tiles_get_name_nobody.get(org.apache.struts.taglib.tiles.GetTag.class);
_jspx_th_tiles_get_6.setPageContext(_jspx_page_context);
_jspx_th_tiles_get_6.setParent((javax.servlet.jsp.tagext.Tag) _jspx_th_c_otherwise_2);
_jspx_th_tiles_get_6.setName("content");
int _jspx_eval_tiles_get_6 = _jspx_th_tiles_get_6.doStartTag();
if (_jspx_th_tiles_get_6.doEndTag() == javax.servlet.jsp.tagext.Tag.SKIP_PAGE) {---------------LINE 1564
_jspx_tagPool_tiles_get_name_nobody.reuse(_jspx_th_tiles_get_6);
return true;
}
_jspx_tagPool_tiles_get_name_nobody.reuse(_jspx_th_tiles_get_6);
return false;
}

See the Line 1564, which is giving the problem.

As mentioned earlier, the same code works on JBoss' earlier version i.e. JBoss 4.0.4

Has JBoss become more stringent in interpreting the TLDs which is causing this problem?
This issue is critical for us as we are planning to use JBoss 4.0.5 GA in production.
