Mockito that comes with spring-boot-starter-test 3.1.x version are failing the unit tests with the following errors: Caused by: org.mockito.exceptions.base.MockitoInitializationException: Could not initialize inline Byte Buddy mock maker. It appears as if your JDK does not supply a working agent attachment mechanism. Java : 17 JVM vendor name : Oracle Corporation JVM vendor version : 17.0.4.1+1-LTS-2 JVM name : Java HotSpot(TM) 64-Bit Server VM JVM version : 17.0.4.1+1-LTS-2 JVM info : mixed mode, sharing OS name : Windows 10 OS version : 10.0 I have Oracle OpenJDK Java 17 installed and everything was working fine before updating to Spring Boot 3.1
