+displayName: Change `java.lang.reflect.Modifier` and ` java.lang.invoke.ConstantBootstraps` method calls to static
+description: >
+  The `java.lang.reflect.Modifier()` and `java.lang.invoke.ConstantBootstraps()` constructors have been removed in Java SE 15 because both classes only contain static methods.
+  This recipe converts the usage of all methods in the two classes to be  static.
+  For more information on these changes, see https://docs.oracle.com/en/java/javase/15/migrate/index.html#GUID-233853B8-0782-429E-BEF7-7532EE610E63
