Payara 6: Server log error when running harvest client, harvest continues to work.

[kcondon]

Server log error when running harvest client, seems to work anyway:
harvest_client_svr_log_err.txt

Adding to 6.0 either to fix or to determine that we won't fix for this release.

Confirmed it happens with p5 when failing to harvest 1 or more datasets. Does not happen when all succeed.
