How to catch ExceptionInInitializerError?

Question

I want to install some kind of global handler to catch any ExceptionInInitializerError which could be thrown from any static block when some class is loading. Currently it dumps a stack trace to the stderr and exits the application. I want to log a stack trace using my logging framework, then exit the application. Is it possible?

It looks like Thread.UncaughtExceptionHandler is what you are looking.

This answer will provide you with more information.

In essence you need to install default exception handler as soon as possible:

        Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
        public void uncaughtException(Thread t, Throwable e) {
            if (e instanceof ExceptionInInitializerError) {
                // do something with you're exception
                // and than close application
                System.exit(-1); // passing 
            }
        }
    });

Thanks, it works. It seems that System.exit isn't necessary, as JVM exits anyway, so I just log exception in the handler. – vbezhenar Jul 03 '16 at 13:47

Maybe you can make a global exception handler and just filter your exception out of it.

Example

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
    public void uncaughtException(Thread t, Throwable e) {
        if (e instanceof ExceptionInInitializerError) {
            //Your handler code
        }
    }
});
