* Repeat Bump dependency.tika.version from 2.1.0 to 2.2.1 Original PR https://github.com/Alfresco/alfresco-transform-core/pull/506 was merged to master where it failed. There had been no build of the PR before the merge, which is why this branch has been created. * Use non deprecated TikaCoreProperties.SUBJECT with tika 2.2.1. The deprecated OfficeOpenXMLCore.SUBJECT value worked in 2.2.0 but not 2.2.1 * With the upgrade of Tika from 2.2.0 to 2.2.1, the deprecated OfficeOpenXMLCore.SUBJECT metadata value became being null and the replacement TikaCoreProperties.SUBJECT became a multi value in a few of our test cases. For backward compatibility with very old versions of Alfresco, we have historically been added a number of extra values including "subject" and "description" back into the raw metadata, before mapping them onto Alfresco properties. These values existed in the original version of Tika used by Alfresco, so it is possible there are custom mappings out there that using them. To complicate matters a little, out standard mappings for some types put the raw "subject" value into cm:description property. What makes it interesting is that the extra "description" value is not used but has the value originally in our expected metadata extarct data. That is why the quick_*_json files have been modified.
