Upload Failing due to Metadata Extraction Issue (Keywords separated by '|')

Technical Description of the issue
Unable to upload attached file. Failing with exception: "Tag Name must not contain | char sequence" (full error along with info with metadata set to debug) is attached as ExtractorException.txt. Other images upload without issue. Looking at IPTC data of image, the Keywords property contains values separated by "|"

Steps to reproduce

1. Install Media Management AMPs to Alfresco 5.1.2
2. Upload attached image
3. Upload Fails with error/stack trace noted in ExtractorException.txt.

Observed Behaviour
See above. Document/Image just fails upload. No error is presented to user. Actual Error is noted in alfresco.log

Desired Behavior
Does not fail at all as this data is part of Image. Extractors handle/ignore any characters that might result in failure

Customer business impact / priority / urgency
Issue is high priority for Nike because upload jsut fails. No indication to user why it fails, etc

Notes:

• Should be reproducible without media management, especially via low-level testing of the ContentMetadataExtracter.
