The first one is that when running with Graal the number of local references reported by JVMTI FollowReferences () to the callback exceeds the size of the array  ( 100 ) the test uses for storing them. The second issue is that the test explicitly checks that the frame depth is in 0..50 range while the frame depth for some of the references reported by the compiler thread may exceed this limit.
