500 Error after database migration succeeds

[Joseph Myers]

I am on a clean install of 4.5.3 trying to migrate from the default database to PostgreSQL. The connection test works and the operation says Database migration successful with the following error (possibly unrelated):

Adding database constraints...
Updating database to latest version...
Switching to new database at: jdbc:postgresql://localhost:5432/crucible...
Complete
Failed to restore ActiveObjects backup :org.postgresql.util.PSQLException: This ResultSet is closed.

After clicking OK, the page refreshes to blank (URL is http://server:8060/admin/database.do) with title FishEye and Crucible - 500 Server Error. On restarting the service I get the following from stderr.txt 

2019-10-22 12:50:22 Commons Daemon procrun stderr initialized

If there is a way to initialize with a PostgreSQL database, instead of being forced to one and then migrating, I may be able to avoid this problem. Anyone have any ideas? Thank you

Update: I tried backup/restore via fisheyectl.bat with similar results. I no longer got the "Failed to restore ActiveObjects backup" error, but the restore operation still throws the above exception (from stdout.txt).

Update 2: Maybe similar to https://community.atlassian.com/t5/Fisheye-Crucible-questions/Crucible-4-3-crash-on-service-start-Application-Context-not/qaq-p/459120
