> JSP scripting does not support Java 8 features (lambdas, method references,
> etc)
> --------------------------------------------------------------------------------
>
> Key: SLING-6458
> URL: https://issues.apache.org/jira/browse/SLING-6458
> Project: Sling
> Issue Type: Bug
> Components: Scripting
> Affects Versions: Scripting JSP 2.0.28, Scripting JSP 2.1.0, Scripting JSP
> 2.1.4, Scripting JSP 2.1.6, Scripting JSP 2.1.8, Scripting JSP 2.2.0,
> Scripting JSP 2.2.2, Scripting JSP 2.2.4, Scripting JSP 2.2.6
> Reporter: Henry Kuijpers
>
> When trying to use Java 8 functionality in a JSP file, the Jasper framework
> in the Sling Scripting bundle fails to compile the JSP file. It seems to get
> stuck on a Java 8 feature: Lambdas.
> {code}
> <%@page session="false" %>
> <%@ page import="java.util.stream.IntStream" %>
> <%@ page import="java.io.IOException" %>
> <%
> out.println("Lambda test");
> IntStream leip = IntStream.of(1, 2, 3, 4, 5, 6);
> final JspWriter out2 = out;
> leip.forEach(x -> {
> try {
> out2.println(x);
> } catch (IOException e) {
> // Intentionally do nothing
> }
> });
> %>
> {code}
> When we remove the complete "leip.forEach" statement, the code compiles and
> executes successfully.
> Upon further investigation, I found out that the Jasper compiler that is
> being used, does not have support for "tag 18", which seems to be the lambda
> feature in Java 8.
> I could find the constant pool tags over here:
> https://docs.oracle.com/javase/specs/jvms/se7/html/jvms-4.html#jvms-4.4-140
> Clearly, there is no support for MethodHandle, MethodType, InvokeDynamic.
> I could find a bug report for Tomcat (where Jasper is developed) over here:
> https://bz.apache.org/bugzilla/show_bug.cgi?id=54475
> It seems that the issue was fixed in a newer version of Jasper, namely
> 6.0.40. We are currently using 6.0.14 (which is in Apache Sling Scripting JSP
> version bundle version 2.1.4).
> I tried looking at
> https://mvnrepository.com/artifact/org.apache.sling/org.apache.sling.scripting.jsp
> but for some reason all newer versions are also embedding Jasper 6.0.14
> (which does not support Java 8) and in the custom code inside that bundle I
> also do not see any cases for 18 in the switch statement in
> SmapUtil$SDEInstaller.copyConstantPool. Nor do I see any traces that look
> like this fix:
> https://bz.apache.org/bugzilla/attachment.cgi?id=31416&action=diff
