JavaFx TableView内容在模糊处理后消失

Question

我已经创建了一个JavaFX应用程序，它有许多TableView来显示内容，如果我运行Jar文件，应用程序可以正常工作。因为我需要分发应用程序给我的客户，所以我的代码应该被混淆。我正在使用Proguard-4.8来混淆我的代码。

我使用Ant创建了一个示例TableView构建脚本，该脚本混淆了示例jar。

在混淆之前只符合jar-

我已经完全运行了。你会发现-

1. build.xml-http://neelamsharma.s3.amazonaws.com/sampleobfuscationbuildscript/build.xml
2. 未混淆的编译Jar-http://neelamsharma.s3.amazonaws.com/sampleobfuscationbuildscript/sample.Jar
3. 模糊Jar-http://neelamsharma.s3.amazonaws.com/sampleobfuscationbuildscript/obfuscated/sampleobfuscated.Jar
4. proguard.map-http://neelamsharma.s3.amazonaws.com/sampleobfuscationbuildscript/obfuscated/obfuscatedproguard.map
5. 源代码Java类-http://neelamsharma.s3.amazonaws.com/sampleobfuscationbuildscript/src/tableviewwithbutton.Java

其他的是-这是我的build.xml文件-

我建议尝试使用PropertyValueFactory的长形式：

col.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Test, String>,
             ObservableValue<String>>() {
     public ObservableValue<String> call(TableColumn.CellDataFeatures<Test, String> t) {
         // t.getValue() returns the Test instance for a particular TableView row
         return t.getValue().testProperty();
         // or
         return new SimpleStringProperty(t.getValue().getMessage());
     }
  });
