We have a custom tag, FormatDateTag extends
org.apache.taglibs.standard.tag.common.fmt.FormatDateSupport. It’s been
working ok for a number of years under tomcat & Oracle JVM. Now, we are moving
to adoptOpenJDK & we are seeing some differences in how tomcat generation of
JSP to Java classes happens when tomcat is doing the EL evaluation. Here is an
example JSP which shows the issue…
<%@ page language="java" contentType="text/html" isELIgnored="false" %>
<%@ page import="java.util.Date" %>
<%@ taglib uri="/WEB-INF/tld/suitags.tld" prefix="sui" %>
<%
Date chdt = new Date();
request.setAttribute("chdt", chdt);
%>
Looking at the compiled JSP source code under Oracle JVM, we see this…
// /tagUnitTests/sui/formatDate/testCaliHDateTime1.jsp(20,0) name = value
type = java.lang.Object reqTime = true required = true fragment = false
deferredValue = false expectedTypeName = null deferredMethod = false
methodSignature = null
_jspx_th_sui_005fformatDate_005f0.setValue((java.lang.Object)
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate("${chdt}",
java.lang.Object.class, (javax.servlet.jsp.PageContext)_jspx_page_context,
null));
The same source compiled using AdoptOpenJDK, we see this…
// /tagUnitTests/sui/formatDate/ testCaliHDateTime1.jsp(20,0) name = value
type = java.lang.Object reqTime = true required = true fragment = false
deferredValue = false expectedTypeName = null deferredMethod = false
methodSignature = null
_jspx_th_sui_005fformatDate_005f0.setValue((java.lang.String)
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate("${chdt}",
java.lang.String.class, (javax.servlet.jsp.PageContext)_jspx_page_context,
null));
As a workaround, we’re adding calls to to convert the String
back to a Date. Has anyone run into this? Any ideas we can try to find the
root cause?
