Value found for #getNonJtaDataSource : not supported

Error message

Value found for #getNonJtaDataSource : not supported

What it means

Same verification path as the JTA case: verifyIgnoredFields rejects non-JTA data sources too. Quarkus does not consume a DataSource from the persistence unit descriptor; all database wiring goes through Quarkus configuration. A non-null getNonJtaDataSource() throws this UnsupportedOperationException (note: message says 'not supported' without 'yet').

Solutions

1. Ensure getNonJtaDataSource() is null; configure the database via quarkus.datasource.* properties instead.
2. Delete setNonJtaDataSource calls from custom descriptor construction code.
3. Bind the persistence unit to a named Quarkus data source using quarkus.hibernate.orm.datasource if multiple data sources exist.

Example fix

// before
descriptor.setNonJtaDataSource(ds);
// after
descriptor.setNonJtaDataSource(null); // let Quarkus wire the datasource via config

if (desc.getNonJtaDataSource() != null) {
    throw new IllegalStateException("Set quarkus.datasource.* config instead of non-JTA datasource on the descriptor");
}

try {
    quarkusBoot();
} catch (UnsupportedOperationException e) {
    if (e.getMessage().contains("getNonJtaDataSource")) {
        log.error("Remove setNonJtaDataSource; let Quarkus wire the datasource");
    }
}

When it happens

Trigger: A PersistenceUnitDescriptor/PersistenceUnitInfo passed into Quarkus boot has setNonJtaDataSource(...) called, e.g. from programmatic bootstrap code mimicking Java SE Hibernate setup.

Common situations: Reusing descriptors from Spring Boot/Java SE Hibernate setups where non-JTA DataSource is standard; helper libraries that populate nonJtaDataSource automatically; tests constructing PersistenceUnitInfo manually with a DataSource.
