Quite a few places that now contain a DirectivesHolder implicitly call `toString` on it in their own `toString` implementations. Before this change that worked just fine, because directives were just a list and lists tend to have reasonable `toString` implementations.\n\nHere is one example:\nhttps://github.com/graphql-java/graphql-java/blob/021fe1b5d2394c979cbb4e7b38839753b99bfffd/src/main/java/graphql/language/ScalarTypeDefinition.java#L116-L121\n\n`DirectivesHolder`, however, does not have one, so all those other `toString` implementations no longer produce reasonable output.\n\n**To Reproduce**\nCreate a ScalarTypeDefinition object. Call `toString` on it.\n\nActual output:\n```\nScalarTypeDefinition{name='Int', directives=graphql.language.NodeUtil$DirectivesHolder@5c995dee}\n```\n\nExpected output (and actual output in 24.x):\n```\nScalarTypeDefinition{name='Int', directives=[]}\n```","author":{"url":"https://github.com/invliD","@type":"Person","name":"invliD"},"datePublished":"2025-12-09T23:02:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/4190/graphql-java/issues/4190"}
