I'm currently working on a Java application using `Jakarta Persistence` with `EclipseLink` and `PostgreSQL`. While setting up the application to test the _database layer_, the persistence configuration is done in such way to automatically create and initialize the database:
```xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence ...>
<persistence-unit name="test">
<properties>
...
<property name="jakarta.persistence.schema-generation.create-script-source" value="database/schema.sql" />
<property name="jakarta.persistence.schema-generation.database.action" value="create" />
<property name="jakarta.persistence.sql-load-script-source" value="database/data.sql" />
...
</properties>
</persistence-unit>
</persistence>
```
The problem I'm facing is with both, `schema.sql` and `data.sql` scripts. There seems to be a _formatting issue_ where every SQL statement must be on its own line for the scripts to be executed correctly — othewise they aren't executed. This has never been an issue with other tools I've used in the past, such as `Liquibase` and `Flyway`.
Anyway, after finding the issue, I thought it was the JPA provider or the database, so I changed them (just to verify) to `Hibernate` and `MySQL`...but regardless, I noticed the exact same issue.
Is there a way to configure JPA to allow multi-line SQL statements in the SQL scripts?

This is an example of the content that's found on both SQL scripts:
```sql
create table table_name_one (id uuid not null, ..., primary key (id));
create table table_name_two (id uuid not null, ..., primary key (id));
-- $projectRoot/src/main/resources/database/schema.sql
```
```sql
insert into table_name_one (id, ...) values (...);
insert into table_name_one (id, ...) values (...);
insert into table_name_two (id, ...) values (...);
insert into table_name_two (id, ...) values (...);
-- $projectRoot/src/test/resources/database/data.sql
