Provide some examples when a finally block won’t be executed in Java?

Usually, finally will be called after the execution of the try or catch code blocks.

The only times finally won’t be called are:

1. If you invoke System.exit()
2. If the JVM crashes first
3. If the JVM reaches an infinite loop (or some other non-interruptable, non-terminating statement) in the try or catch block
4. If the OS forcibly terminates the JVM process; e.g., kill -9 <pid> on UNIX
5. If the host system dies; e.g., power failure, hardware error, OS panic, et cetera
6. If the finally block is going to be executed by a daemon thread and all other non-daemon threads exit before finally is called
