Prior to v20, the original resource index string would be passed to such that any call to resource.getInstance() would return that string.

For v20, changes were made so those strings are passed through GenericTypeResource.sanitizeInstance() to sanitize their values, by replacing whitespace, colon, backslash, and square brackets with underscores.

This is causing problems for the new ObjectNameStorageStrategy which expects to be passed the original string, not the sanitized version.
