VMWare + JavaFX + Mac“hello world”应用无法安装/执行

Question

I'm posting here after much study of all the previous postings (on this site and elsewhere) regarding problems in running a JavaFX application (developed using JWrapper as the launcher) in a VMWare encapsulated instance of Mac OSX 10.10. [NOTE: edited the preceding sentence and the title of this posting on 2015-02-25 to add reference to VMWare.]

After experiencing failure of my much larger Java 1.8.0_25 application to install and launch in Mac OSX v10.10.1, I replicated the problem using a 3-line "Hello World" JavaFX application.

In both cases, I am using what seem to be the standard Mac-oriented parameter settings in the JWrapper build-parm XML:

<JvmOption>-Djavafx.macosx.embedded=true</JvmOption>
<MustFork>true</MustFork>

In both cases, when attempting installation on the Mac, the JWrapper splash screen appears as expected, but then it goes away, and the application itself fails to launch.

Here are the links to (1) zip file with all logs from an attempted "HelloWorldFX" installation on Mac OSX v10.10.1, and (2) zip file with the log and "build" folder from the application's JWrapper build process. Note that this application installs and runs fine in Windows and Ubuntu.

Logs: https://googledrive.com/host/0B0skoeyva4KiUDZBS1FSUXo4RUU/mac_logs.zip

Build folder (300MB): https://googledrive.com/host/0B0skoeyva4KiUDZBS1FSUXo4RUU/helloWorldFX_build_folder.zip

Here are the highlights:

The HelloWorldFX code (pretty much the entirety of the application):

public void start(Stage stage) {
    stage.setTitle("Hello World FX");
    stage.setScene
        (new Scene(new StackPane(new Button("Hello World FX")), 600, 250));
    stage.show();
}

My complete JWrapper build parms:

An ominous message from the "Wrapper" log file on the Mac:

+1 [BundleLoader] Could not load JRE bundle!

One curious line from the "Generic Updater" log file on the Mac, in which a file name is apparently truncated by JWrapper, resulting in a file not found exception:

8574158 (+0) java.io.FileNotFoundException: /Users/admin/Library/Application Support/JWrapper-HelloWorldFX3/JWrapper-JWrapper-00033253833-complete/JWAppSpec- (No such file or directory)

Any assistance with getting this problem resolved would be GREATLY appreciated!!

Answer 1

All this launch looks OK, the fact that the HelloWorldFX3 log was produced at all would indicate that the app did launch.

The message 'Disabling App Nap' is just the last message that JWrapper prints before it hands over control so that doesn't indicate that it failed to launch.

Do you get any hs_err_pid files generated anywhere?

What is the main method for your app like, are you able to put in a printout and check if it reaches that point in the logs?

My best guess at this point would be that although you have NoStripJRE specified maybe you haven't deleted the pre-built JRE archives from your build folder? If not then JWrapper will continue to use those and won't rebuild them and you won't have the JavaFX components to allow your app to run. I would suggest removing those and rebuilding and giving that another whirl. Beyond that if there is a hs_err_pid file it may have more info.
