Hey @romani
The tests are failing on Java 21 due to a Byte Buddy compatibility issue:

Java 21 (65) is not supported by the current version of Byte Buddy which officially supports Java 20 (64)

Root Cause:

mockito-inline:5.2.0 is deprecated and was the last published version of that artifact ,It bundles Byte Buddy 1.14.1, which only supports up to Java 20 (Java 21 requires Byte Buddy 1.14.3+)
