Question

I have been searching for an answer to if it’s possible to backtrack when doing Java debugging. For instance if I have the code:

int x = 1
int y = 0

//Exception will happen here
int z = x/y

And if I’m hitting the exception, I would like to go back.
And not just like dropping the frame, but also revert actual changes made to the Heap.
Is that currently possible?

Thanks in advance.

There is tool called Chronon Time Travelling Debugger

It claims…

Overview

The Chronon Time Travelling Debugger allows you to playback Chronon
recordings and easily find root cause of defects. It is specifically
built from the ground up to allow debugging of long running programs
that run for days/months and are highly multithreaded.

The debugger plugs seamlessly into Eclipse adapting itself naturally
to your workflow. You can also use the Eclipse integration of the
Chronon Debugger to easily record programs on your development
machines from within Eclipse.
