Having a double quote (escaped) in the tocitem/@text attribute breaks TOC panel loading in the Help Panel

[glassfishrobot]

Version is 2.0_02.

When having a title that ends in a double quote, then the TOC is not loaded, because of:

Parsing failed for jar:file:/D:/programs/Oxygen%20XML%20Editor%2018/lib/editorHelp.jar!/toc.xml
<tocitem text="When Started, Windows Service Reports "Error 1067: Process Terminated Unexpectedly""
           target="windows-service-reports-error-1067"/>
Exception in thread "Thread-3" java.lang.NullPointerException

The toc.xml file is wellformed and has the content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE toc
  PUBLIC "-//Sun Microsystems Inc.//DTD JavaHelp TOC Version 1.0//EN" "http://java.sun.com/products/javahelp/toc_1_0.dtd"> <toc version="2.0">

               target="service">
         ...
      </tocitem>
   </tocitem>
</toc>
