I tried to setup a unit test with h2-db and the new spring boot 3.

Starting the tests results in 100+% CPU and random console output.

openjdk 17.0.5 2022-10-18
OpenJDK Runtime Environment (build 17.0.5+8-Ubuntu-2ubuntu120.04)
OpenJDK 64-Bit Server VM (build 17.0.5+8-Ubuntu-2ubuntu120.04, mixed mode, sharing)

There is a dependency with Collection of Abstract Entities. If i remove the Collection<Abstract> then everything work fine again.
