JavaFX Fatal error JRE (Oracle Java 8 update 91)

Question

I've been experiencing this strange issue for a while now. I'm making a JavaFX application which has a login screen.

The issue is that whenever I press enter after putting in the username and password, I encounter the following fatal error. It works fine if I use the Login button.

Full error log here.

Following are the action listeners for username field and password field which detect ENTER key press:

fieldUsername.setOnKeyPressed((KeyEvent event) -> {
    if (event.getCode() == KeyCode.ENTER) {
        KeyEvent.fireEvent(buttonLogin, new MouseEvent(MouseEvent.MOUSE_CLICKED, 0, 0, 0, 0, MouseButton.PRIMARY, 1, true, true, true, true, true, true, true, true, true, true, null));
    }
});

fieldPassword.setOnKeyPressed((KeyEvent event) -> {
    if (event.getCode() == KeyCode.ENTER) {
        KeyEvent.fireEvent(buttonLogin, new MouseEvent(MouseEvent.MOUSE_CLICKED, 0, 0, 0, 0, MouseButton.PRIMARY, 1, true, true, true, true, true, true, true, true, true, true, null));
    }
});

I'm firing the login button whenever I encounter an ENTER key press.

And following is the action listener for buttonLogin:

buttonLogin.setOnMouseClicked((MouseEvent event) -> {
    CheckLoginAndPin c1 = new CheckLoginAndPin();
    if (!fieldUsername.getText().isEmpty() && !fieldPassword.getText().isEmpty()) {
        if (c1.checkUsername(fieldUsername.getText())) {
            if (c1.login(fieldUsername.getText(), fieldPassword.getText())) {
                ArrayList<String> arrayListGetUserDetails = c1.getPriviledge(fieldUsername.getText());
                stageLogin.close();
                MainFrame mainFrame = new MainFrame(arrayListGetUserDetails.get(0), arrayListGetUserDetails.get(1), arrayListGetUserDetails.get(2), fieldUsername.getText());
            } else {
                PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "Password incorrect", fieldPassword, 100, 60);
            }
        } else {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "User name incorrect", fieldUsername, 100, 60);
        }
    } else {
        if (fieldUsername.getText().isEmpty() && !fieldPassword.getText().isEmpty()) {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "User name can not be empty", fieldUsername, 100, 60);
        } else if (fieldPassword.getText().isEmpty() && !fieldUsername.getText().isEmpty()) {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "Password can not be empty", fieldPassword, 100, 60);
        } else if (fieldUsername.getText().isEmpty() && fieldPassword.getText().isEmpty()) {
            PopupErrorMessage popupErrorMessage = new PopupErrorMessage(stageLogin, "User name & password can not be empty", fieldUsername, 100, 60);
        }
    }
});

What am I doing wrong here?

You might want to check [this](http://stackoverflow.com/questions/28982396/failed-to-write-core-dump-core-dumps-have-been-disabled) out. Are you using [eclipse](http://stackoverflow.com/questions/19332489/how-to-fix-failed-to-write-core-dump-core-dumps-have-been-disabled-error-whil)? — 0x6C38, May 29 '16 at 07:03
@MrD Dude, I answered that. Increasing the size of the core dump won't solve this issue. — UrsinusTheStrong, May 29 '16 at 07:05
*"/usr/lib/jvm/java-8-oracle"* sounds like a binary blob from oracle, which aiui has some differences to openjdk builds. Have you tried a jre compiled by your distro's maintainers? — the8472, May 29 '16 at 10:47
Now that I notice, It isn't using OpenJDK 8. I've two JDKs installed. Let me check. — UrsinusTheStrong, May 29 '16 at 10:48
The native stack looks similar to [JDK-8087368](https://bugs.openjdk.java.net/browse/JDK-8087368) and the submitted testcase seems unreliable. If yours reproduces 100% that might help them with fixing. — the8472, May 29 '16 at 10:59
Ok, I'll check with OpenJDK then. Thanks for pointing it out. — UrsinusTheStrong, May 29 '16 at 11:00
Unable to run it with OpenJDK. Giving an error "Unable to locate Login.Login" (My Main class). Also, Netbeans not recognizing OpenJDK after adding OpenJDK through platform manager. Also, OpenJDK lacks source packages. — UrsinusTheStrong, May 29 '16 at 11:23
@the8472 After, some tinkering, I was able to change the JDK of the project to OpenJDK. I still wasn't able to run it because there are no JavaFX sources in case of OpenJDK like that in Oracle JDK. — UrsinusTheStrong, May 29 '16 at 12:24
Wild stab in the dark, but JDK 8 u91 is pretty old. Maybe try it on the latest available, update u171, and see if someone fixed the problem since u91. You never know... — Speakjava, Jun 14 '18 at 16:59
