[jira] [Updated] (CONNECTORS-1603) Global config XML double-decoded when stored in Zookeeper

     [ https://issues.apache.org/jira/browse/CONNECTORS-1603?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Raman Gupta updated CONNECTORS-1603:
------------------------------------
    Description: 
When using Zookeeper to store the global config, it is impossible to have entities in the input XML. For example if we have a db password with value "foo&bar", then we have to encode this in the global config XML like this:

  <property name="org.apache.manifoldcf.dbsuperuserpassword" value="foo&amp;bar"/>

When writing the global config to Zookeeper, it appears like this XML file is parsed, but then written to ZooKeeper as:

  <property name="org.apache.manifoldcf.dbsuperuserpassword" value="foo&bar"/>

Now, when this global config is read from ZooKeeper, Manifold parses it as XML again, and of course fails with the error:

{{Caused by: org.xml.sax.SAXParseException; lineNumber: 31; columnNumber: 81; The reference to entity "bar" must end with the ';' delimiter.
        at org.apache.xerces.parsers.DOMParser.parse(Unknown Source)
        at org.apache.xerces.jaxp.DocumentBuilderImpl.parse(Unknown Source)
        at java.xml/javax.xml.parsers.DocumentBuilder.parse(DocumentBuilder.java:122)
        at org.apache.manifoldcf.core.common.XMLDoc.init(XMLDoc.java:359)
        ... 9 more
}}
