Warning: RecomputeFieldValue.ArrayIndexScale automatic substitution failed. The automatic substitution registration was attempted because a call to sun.misc.Unsafe.arrayIndexScale(Class) was detected in the static initializer of io.netty.util.internal.PlatformDependent0. Detailed failure reason(s): The field java.lang.Long.value, where the value produced by the array index scale computation is stored, is not static.
Warning: RecomputeFieldValue.FieldOffset automatic substitution failed. The automatic substitution registration was attempted because a call to sun.misc.Unsafe.objectFieldOffset(Field) was detected in the static initializer of io.netty.util.internal.PlatformDependent0. Add a RecomputeFieldValue.FieldOffset manual substitution for io.netty.util.internal.PlatformDependent0.ADDRESS_FIELD_OFFSET. Detailed failure reason(s): The argument of Unsafe.objectFieldOffset() is not a constant field.
