This looks like an issue with the grammar. My guess is it isn't properly
handling white space at the end. If you change the variable
`hllpDefaultConstructorRule` to the below, it should work. I know this isn't a
permanent solution, but it narrows the problem down.
```
/**
*HLLP_CARDINALITY(
* HLLP_ADD(
* HLLP_ADD(
* HLLP_INIT(),
* val1
* ),
* val2
* )
* )*/
@Multiline
private static String hllpDefaultConstructorRule;
```
