In the schema generation, Hibernate 5 creates the indexes using an explicit schema. This fails as Postgres doesn't like the fully qualified index name:

Hibernate:
create index public.bugreports_created_index on public.bugReports (created)
Tests run: 3, Failures: 0, Errors: 2, Skipped: 0, Time elapsed: 2.04 sec <<< FAILURE! - in com.seanergie.util.ApplicationSettingsTest

This SQL statement works

create index bugreports_created_index on public.bugReports (created);

while the one created by Hibernate fails
create index PUBLIC.bugreports_created_index on public.bugReports (created);

It used to work with Hibernate 4.x.

This is similar to this bug in Liquidbase:
