Thanks. Sorry, for last one, could you check:
java.util.Map lhm = new java.util.LinkedHashMap<>();
Class c = lhm.getClass();

Looks the same:
java TestForStruts
COPY ME 1: public abstract int java.util.Set.size()
COPY ME 2: 0

Sorry. Could you please check this updated one which is OK here:
public static void main(String[] args) throws Exception
{
java.util.Map lhm = new java.util.LinkedHashMap<>();
Class c = lhm.getClass();
java.lang.reflect.Method m = c.getMethod("keySet");
Object k

This is the latest IBM JDK 8. Or at least the latest that works with our
version WebSphere, but it's very recent. The build date

Could you check with latest version of IBM JDK 8? And are you maybe able
to check also with Oracle and OpenJDK 8?

Yes, sorry.
I did not try the latest Freemarker, I'm using what is packaged with Struts
(min-lib.zip). Which, even at the very latest 2.5.16, is apparently
2.3.2
You mean ? There is no tag. Did you
try to use the latest Freemarker version?
I have tested the tag with Oracle Java 8 and it works without issue.
Look like incompatibility between IBM Java and Freemarker.

Struts 2.5.14.1, WebSphere 8.5.5.13, IBM Java 8 (level 1.8.0_161) on AIX.
We have a JSP with a plain element that works without issue
when we switch WebSphere back to Java 7, but in Java 8 produces the following
error:
2018-05-22 12:43:24,384 ERROR [freemarker.runtime]: error - Error executing
