現在のプロジェクトで次のコードを使用してダイアログ ボックスを開きます。controlfx とその素晴らしいダイアログ ボックスについて読んだので、プロジェクトでそのコードを使用しましたが、エラーが発生し、理由がわかりません。
Dialogs.create()
.owner(SchoolManagement2.stage1)
.title("Information Dialog")
.masthead("Look, an Information Dialog")
.message("I have a great message for you!")
.showInformation();
次のjarを追加しました
controlsfx-8.0.6_20.jar
controlsfx-samples-8.0.6_20.jar
fxsampler-1.0.6_20.jar
次のエラーが表示されます:

エラーが表示ControlsFX Error: ControlsFX 8.0.6_20 requires at least Java 8u20
されるので、インストールjdk-8u20-ea-bin-b22-windows-x64-08_jul_2014.exe
しましたが、エラーは同じままです。
私を助けてください。
