This is a reproducer project for a bug introduced in Quarkus 3.8.1 and agroal 2.3 that prevents from using multiple persistence units within a single transaction.
This project has 2 submodules. Both contain exactly the same code and configuration properties. The only difference between the two is the version of Quarkus:
quarkus-3.8.1uses Quarkus 3.8.1. This was made to show that the example works in this version.quarkus-3.8.2uses Quarkus 3.8.2. This is the actual reproducer.
Both submodules contain a command mode application that attempts to insert 2 random records in two different databases within a single transaction.
One database is associated to the default persistence unit,
the other is associated to the persistence unit named other.
- Docker (for the dev service databases)
- JDK 17+
Run a submodule with one of the following commands:
./mvnw compile quarkus:dev --pl quarkus-3.8.1./mvnw compile quarkus:dev --pl quarkus-3.8.2No other configuration should be needed.
On quarkus-3.8.1, the application terminates without any error. The two records have been successfully
inserted on their respective databases.
On quarkus-3.8.2, the application fails by throwing an exception. The root cause is:
java.sql.SQLException: Unable to enlist connection to existing transaction
