I am writing chat App in javaFx..and I am using eclipse IDE.. My Application is running well but I don't know why suddenly application has been stopped.

Answer 1

It sounds like you're running JavaFX with Java 8 on Linux, and you've run into this bug:

https://bugs.openjdk.java.net/browse/JDK-8141687

App crashes while starting Main.class in JavaFx

ava version "1.8.0_60" Java(TM) SE Runtime Environment (build 1.8.0_60-b27) Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

ADDITIONAL OS VERSION INFORMATION : Mint17.2 Cinnamon 64Bit

SUGGESTION: Try a different version of Java/JavaFX.

1. Run sudo update-alternatives --config java to see what alternatives are already present on your system. I would downgrade to Java 1.7 if possible.

2. If there are no suitable candidates, use apt-get install openjdk-7-jdk :

Answer 2

I had the same issue (except that it was java-8-oracle build 101) and found out why it was happening:

I have a login screen that appears before my main application and that screen gets closed after the login occurs and, apparently, closing it (or even hiding it) and showing a new window makes it crash.
