public class ForkedJvmExtension
extends Object
implements InvocationInterceptorJUnit 5 InvocationInterceptor backing the ForkedJvm annotation. When applied, the test method is skipped in the current JVM and re-run in a freshly forked JVM via ForkedJvmTestRunner, with any declared system properties and JVM args.
Recursion is avoided by setting the system property ForkedJvmTestRunner.FORKED_FLAG on the child; when the extension sees that flag set in the current JVM it just proceeds with the normal invocation (i.e. the child JVM actually runs the test body).
