Description

During testing of the urn:node:mnTestSEAD MN, two objects (sead-Martin-John-f1dbc3df-c27c-4647-b05a-4b1f05c99a24 and seadva-ZhouQuan388469d5-33bb-491c-867b-c515ff715594) were only partially synchronized (see attached files) on cn-stage when the system metadata for each object was found to be missing the "dateUploaded" field. Each object and corresponding system metadata are available through the REST API (it is hypothesized that the system metadata only resides in the memory part of the Hazelcast Map) and the object was written to Metacat storage (see below); however, the object's system metadata failed to be stored by Metacat due to an Null Pointer Exception resulting from the missing field (see below).

Metacat should not allow partial object storage when the object's system metadata is incomplete and fails to be recorded in the appropriate system metadata table.
