Cannot escape double quotes in Lucene searches

I am wondering if you could give me a patch regarding the Jira#ETWOTWO-1138 since I can see the following description in the Jira#ETWOTWO-1138, which is saying Michael Shavnev seems fixed the problem and emailed the patch to you, but it has not been attached in the Jira yet.

We have fixed a it by change the 'QUOTED' token in QueryParser.jj. We used a JavaCC Version 3.2 to generate appropriate parser files. Patch has been emailed to Gav.
====================================================================

Actually I am handling the ticket#15024-22137. What the customer wants to do is the following lucene indexing search, but they both does not work.
+PATH:"/app:company_home/cm:apptest/*" AND +@cm\:name:"Helmut \"B"
+PATH:"/app:company_home/cm:apptest/*" AND +@cm\:name:"Helmut "B"
+PATH:"/app:company_home/cm:apptest/*" AND +@cm\:name:Helmut "B

I want to know if Michael's patch can solve this or not,(The Jira status is open) I checked a source code for QueryParse.jj on the latest Alfresco version, which showing as follows, I am wondering whether or not this is the same as Michael Shavnev's modified one.

<QUOTED: "\"" (~["\""] | "\\\"")+ "\"">

Best Regards,
