MRE for micronaut-core issue 7887

This repository represents a minimal, reproducible example, showing Micronaut failing to start up in versions 3.6.0 and 3.6.1, with default configurations.

This MRE relates to the following GitHub issues:

• https://github.com/micronaut-projects/micronaut-core/issues/7887
• micronaut-projects/micronaut-core#7869

Hints about the MRE

Reproducing the error should be as simple as running ./gradlew run, using Java 11 or higher (8 would probably work too).

Following the expected failing output:

$ ./gradlew run

> Task :run FAILED

Some notes about what was required to reproduce this error:

• Eager singleton initialization has to be enabled. See com.example.Application line 8.
• A data-source has to be configured for the EntityManager bean to exist, see application.yml.
• At least one bean has to depend on the EntityManager bean. See com.example.ErrorTrigger line 11.

We are unsure whether injecting EntityManager is the only way of triggering the issue.
