help you fix your problem The problem I think is that even with AOP you can not intercept the exception consumption process. With AOP you could capture, say, all of the exceptions that are created, but you can't know when they're consumed. For example: try {
...
} catch (Exception e) {
log.boom("Ouchies happened here", e);
}

Catch Segfault or any other errors/exceptions/signals in C++ like catching exceptions in Java

this will help You cannot reliably resume execution after a segmentation violation. If your program must remain running, fence off the offending library in a separate process and communicate with it over a pipe. When it takes a segmentation violation, your program will notice the closed pipe.

Throwing custom exceptions in Java versus built in exceptions

Does that help NoSuchElementException is a RuntimeException (un-checked exception) and we don't need to handle or declare RuntimeExceptionS, thus the compiler wont complain, but instead throw it at runtime. In the case of checked exceptions i.e., all the exceptions which are not subtypes of RuntimeException, the compiler will check for a suitable catch clause, enabling the program to continue its course of execution, after performing the operations within the catch; to do this, you need to handle them using try/catch blocks or declare them using the throws clause - delegating the responsibility of handling the exception higher up the call chain. If your custom exception is not a RuntimeException rules of checked exceptions apply to your custom exception as well.

Catching Unknown Exceptions With C#

should help you out As noted in the comments (I guess I should have read those before I started typing up an answer...) When an application throws an exception that is unhandled, it fires the UnhandledException event just before death and you can subscribe to that in order to log any details that will help you figure out what happened.

How to wrap checked exceptions but keep the original runtime exceptions in Java

this will help I use a "blind" rethrow to pass up checked exceptions. I have used this for passing through the Streams API where I can't use lambdas which throw checked exceptions. e.g We have ThrowingXxxxx functional interfaces so the checked exception can be passed through. This allows me to catch the checked exception in a caller naturally without needing to know a callee had to pass it through an interface which didn't allow checked exceptions. try {
// some code that can throw both checked and runtime exception
} catch (Exception e) {
throw rethrow(e);
}
public void loadFile(String file) throws IOException {
// call method with rethrow
}
/**
* Cast a CheckedException as an unchecked one.
*
* @param throwable to cast
* @param <T> the type of the Throwable
* @return this method will never return a Throwable instance, it will just throw it.
* @throws T the throwable as an unchecked throwable
*/
@SuppressWarnings("unchecked")
public static <T extends Throwable> RuntimeException rethrow(Throwable throwable) throws T {
throw (T) throwable; // rely on vacuous cast
}
