1.3.0Alpha1 cannot initially find JDBC Driver on Java8, but works on Java11

[sean-scott-lr]

Describe the bug
When using 1.3.0Alpha1 with Java8, during startup I see the following error:

2020-02-07 08:14:19,867 WARN  [io.agr.pool] (Agroal_8663792271) Datasource '<default>': Unable to find a driver that accepts url: jdbc:postgresql://localhost:5432/__dbSchemaName__

However, shortly after this error Quarkus attempts to load again and succeeds.

This looks odd:

Caused by: java.sql.SQLException: Unable to find a driver that accepts url: jdbc:postgresql://localhost:5432/__dbSchemaName__
	at io.opentracing.contrib.jdbc.TracingDriver.findDriver(TracingDriver.java:132)
	at io.opentracing.contrib.jdbc.TracingDriver.connect(TracingDriver.java:68)
	at io.agroal.pool.ConnectionFactory.createConnection(ConnectionFactory.java:200)

Not sure why it's using io.opentracing.contrib.jdbc.TracingDriver to connect. Can you share an application which reproduces this?

[sean-scott-lr]

We are using the tracing driver.
quarkus.datasource.url=jdbc:tracing:postgresql://localhost:port/dbSchemaName

Works in 1.2.0.Final Java8 and Java11
Doesn't work in 1.3.0.Alpha1 Java8 but does in Java11

The issue is described launching the application in dev mode. What happens when you build it and launch it from the JAR?

[sean-scott-lr]

So, I had to skip tests to build the jar because the issue happens during test too. However, I was able to run the jar with JDK8 successfully once I was able to build it.

Thanks for this info.

This is a genuine issue. I've opened #7089 with a potential fix.
