Hi Pete,
It's a jdk/maven setup problem I think.
Can you try, these commands (without the $):
$ echo %JAVA_HOME%
= should give something like C:\... and it should be a JDK, not a JRE
$ java -version
java version 1.6.0_16
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)

I have never gotten any of my rules to compile using mvel strict mode. If I
leave the default I get spews of error messages that I can't make any sense

---
package systeminsights.plugin.core.schedule
rule foo
when
eval(true)
then
// noop
end

I get messages like

Yes, the above example had a typo:
System.out.println(*** f= f())
Was really when I ran the test:
System.out.println(*** f= + f())

Interesting, if I change from mvel to java and remove the package statement:
function String f() {
return function;
}
rule Invoke function
when
eval(true)
then
System.out.println(*** f= + f());
end

Then this works.
So then, what permutations of mvel/java actually work:

drools 5.1
mvel 2-2.0.14
