The new messages for reflection look like:

Cannot reflectively access the class 'HelloWorld$TargetClass'. To allow this operation, add the following to the 'reflection' section of the 'reachability-metadata.json' and rebuild the native image:

   {
     "type": "HelloWorld$TargetClass"
   }

The 'reachability-metadata.json' file should be located in 'META-INF/native-image/<group-id>/<artifact-id>/' of your project. For further help, see https://www.graalvm.org/latest/reference-manual/native-image/metadata/#reflection

Cannot reflectively access the proxy class inheriting ['java.lang.Runnable']. To allow this operation, add the following to the 'reflection' section of the 'reachability-metadata.json' and rebuild the native image:

   {
     "type": {
       "proxy": [
         "java.lang.Runnable"
       ]
     }
   }

The 'reachability-metadata.json' file should be located in 'META-INF/native-image/<group-id>/<artifact-id>/' of your project. For further help, see https://www.graalvm.org/latest/reference-manual/native-image/metadata/#reflection

Cannot reflectively access the lambda-proxy class declared in 'HelloWorld' inheriting ['java.lang.Runnable']. To allow this operation, add the following to the 'reflection' section of the 'reachability-metadata.json' and rebuild the native image:

   {
     "type": {
       "lambda": {
         "declaringClass": "HelloWorld",
         "interfaces": [
           "java.lang.Runnable"
         ]
       }
     }
   }

The 'reachability-metadata.json' file should be located in 'META-INF/native-image/<group-id>/<artifact-id>/' of your project. For further help, see https://www.graalvm.org/latest/reference-manual/native-image/metadata/#reflection

And for resources:

Cannot access resource at path 'path/to/resource'. To allow this operation, add the following to the 'resources' section of the 'reachability-metadata.json' and rebuild the native image:

   {
     "glob": "path/to/resource"
   }

The 'reachability-metadata.json' file should be located in 'META-INF/native-image/<group-id>/<artifact-id>/' of your project. For further help, see https://www.graalvm.org/latest/reference-manual/native-image/metadata/#resources

Other access will have a similar shape.
