Summary: Hibernate Core 5.4.32.Final issue resulting in no
database connection
Key: KARAF-7356
URL: https://issues.apache.org/jira/browse/KARAF-7356
Project: Karaf
Issue Type: Bug
Components: karaf
Affects Versions: 4.2.14
Reporter: Ashish Khaware
Apache Karaf 4.2.14 is bundled with hibernate-core 5.4.32.Final version. But
there seems some issue in fetching the database connection.

org.hibernate.orm.core - 5.4.32.Final | HHH000342: Could not obtain connection

org.hibernate.HibernateException: Unable to determine Dialect to use [name=,

persistence.xml appears like this:

<properties>
<property name="hibernate.id.optimizer.pooled.prefer_lo"

</properties>
</persistence-unit>
</persistence>
{code}
I believe dataSource is not available and hence this error is coming. All
required parameters are passed through configuration (like username, password,
schema etc..)
*IMPORTANT:*
As I am upgrading from Apache Karaf 4.2.9 to 4.2.14 (and to 4.2.15 tomorrow), I
have observed that in 4.2.9 JdbcEnvironmentInitiator > initiateService() was
getting called twice, where connection was getting established in 2nd iteration.
In 4.2.14, there is just one invocation and database connection is not
established.
Can someone please investigate?
