Dumping a Java program into a file and restarting it

Question

I was just wondering if it's possible to dump a running Java program into a file, and later on restart it (same machine)

It's sounds a bit weird, but who knows

Yes, this is the hibernate feature for a process instead of a full system. But google 'hibernate jvm process' and you'll understand my pain.

There is a question for linux on this subject (here). Quickly, it's possible to hibernate a process (far from 100% reliable) with CryoPID.

A similar question was raised in stackoverflow some years ago.

With a JVM my educated guess is that hibernating should be a lot easier, not always possible and not reliable at 100% (e.g. UI and files).

Serializing a persistent state of the application is an option but it is not an answer to the question.

Answer 1

This may me a bit overkill but one thing you can do is run something like VirtualBox and halt/save the machine.

There is also:
- JavaFlow from Apache that should do just that even though I haven't personally tried it.
- Brakes that may be exactly what you're looking for
