or in other words Activations with newer data take priority over
activations with older data.

That is correct LIFO behaviour - last in first out.

The agenda, when calling getNextFocus, calls getLast(). Which causes
the consequences to be executed in reverse order. Is there a reason
for that?
For example, the following example....
public static void main(String[] args) throws Exception {
StringBuffer rules = new StringBuffer();
rules.append("package example;\n")
.append("import java.lang.Integer;\n")
.append("rule \"Count\"\n")
.append("when\n")
.append("i : Integer()\n")
.append("then\n")
.append("System.out.println(i);\n")
.append("end\n");
System.out.println(rules);
final PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl(new StringReader(rules.toString()));
final RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage(builder.getPackage());
final WorkingMemory workingMemory = ruleBase.newWorkingMemory();
for (int i = 0; i < 10; i++) {
workingMemory.assertObject(new Integer(i));
}
workingMemory.fireAllRules();
}
Will print out...
