> This seems to be because the ConditionAnalyzer wants to throw a RuntimeException (line 229):
> if (accessor == null) {
>             throw new RuntimeException("Null accessor on node: " + node);
> }
> Then the toString of ASTNode node crashes with a NullPointerException at line 427:
> public String toString() {
>     return isOperator() ? "<<" + DebugTools.getOperatorName(getOperator()) + ">>" :
>         (PCTX_STORED & fields) != 0 ? nameCache : new String(expr, start, offset);
> }
> This is because the variable expr is null.
