apoc.cypher.runFile() - Unexpected behaviour with commented ";"

[Bastien Hubert]

Expected Behavior (Mandatory)

In a cypher file, when I comment a line containing ";", apoc.cypher.runFile() should execute all the other statements contained in the file.

Actual Behavior (Mandatory)

When I comment a line containing a ";", the statements below this line are not executed by the procedure.

How to Reproduce the Problem

Steps (Mandatory)

1. Take a simple cypher file:

 RETURN "Step 1";
 RETURN "Step 2";
 RETURN "Step 3";

2. Comment a statement in the file:

 RETURN "Step 1";
 // RETURN "Step 2";
 RETURN "Step 3";

3. Run this file using apoc.cypher.runFile() => the "step 3" statement is not executed anymore

4. Remove the semicolon of the commented line:

 RETURN "Step 1";
 // RETURN "Step 2"
 RETURN "Step 3";

5. Run this file using apoc.cypher.runFile() => the "step 3" statement is now executed
