JavaFx TableView contents are disappeared after obfuscation - ant

Question

I have created one JavaFX application that have many TableView to show content, application works fine if I run Jar file. As I need to distribute application to my clients so my code should be obfuscated. I am using Proguard-4.8 for obfuscation of my code.
I have created one sample TableView build script using Ant that obfuscate sample jar.
Before Obfuscation complied jar only -
After Obfuscation Jar -
I have uploaded my complete build script project at -
http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript.zip
I have completely run it. You will find -
build.xml -
http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/build.xml
Compiled Jar without obfuscation - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/Sample.jar
Obfuscated Jar - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/obfuscated/SampleObfuscated.jar
Proguard.map - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/obfuscated/ObfuscatedProguard.map
Source Java Class - http://neelamsharma.s3.amazonaws.com/SampleObfuscationBuildScript/src/TableViewWithButton.java
Other things is that -
This is my build.xml file -

In build.xml if I add this lines then I am able to see TableView Contents, but it do not obfuscate all public classes and their methods.
<keep access="public">
<method access="public protected" />
</keep>
I need my project completely obfuscated. Is there other way to obfuscate jar file without keeping public classes UN-obfuscated so that I am able to see TableView text completely.
Thanks,

Answer 1

I suggest trying to use the long form of PropertyValueFactory:
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());
}
});
