Github user ottobackwards commented on the issue:
https://github.com/apache/metron/pull/814
for example:
```java
@Test
public void testValidation() {
Object value = run("IF x == null THEN THROW('it cannot be null') ELSE
'it is ok'", new HashMap(){{
put("x","something");
}} );
}
```
This is a valid test, but it fails on validation not parse.---
