Any idea what's up with this?

In addition, this corrupted my craftbukkit.jar. I had to redownload.

 

Sun Java is more compatible, so maybe use that if you will not be able to find the reason for this error.

 

Personally, I've had more success running my client and my server with OpenJDK (every once in a while SunJAva would crash, but OpenJDK never had issues).

Though I don't program in Java, so take my statement with a grain of salt.

However, switching the flavor of Java you're using is certainly a good way to troubleshoot the problem.

 

I have run both sun and open on my ubuntu 10.10 box, neither is better or worse for compatibility in my experience, it is just a preference, although if your linux distro uses one as default the default may work better for you, they both work, most of time things not working right is due to an incompatibility with craftbukkit and your plugins or just with craftbukkit if you are running no plugins.

 

OpenJDK was already installed and I didn't want to change it - what makes me curious is the fact that craftbukkit.jar somehow got corrupted in the process. What was Bukkit trying to do that this could've somehow been caused by?

 

That's highly, i mean HIGHLY improbable to be a bukkit bug. That'S why I'm talking about java flavor.

 

Maybe so, but Java doesn't randomly just derp and delete the jar it's running.

 

It's possible it was a hardware fault that caused the problem.

 

I am really curious, why is this the case, I have had craftbukkit explode a list of bull from one end of my screen to the other. Running both sun and open, running 17 20 and 23. bukkit is and can be quite unstable so why is it highly improbable that bukkit did not fall on its own metaphorical sword and eat itself for lunch?

I really am curious I may sound a bit sarcastic but I like information and if there is something I don't know I want to learn about it.

 

Bukkit being unstable is one thing, of course there are bugs.
But the craftbukkit.jar is just the "executable" (quoted on purpose because it is not per se). And you don't edit the executable, it's just loaded and then run and never touched.
To touch and destroy it would mean opening it for writing on purpose, that's why it's highly improbable.

 

Cool, thanks for the info and explanation.

 

Yeah, but something did open and try to write to it, regardless of probability, which is why it makes no sense to me.

 

any chance you are running some sort of startup script or wrapper? or bukitup/similar?
any of those might try to update (and thus modify) the jar

 

No, nothing that should be modifying the jar, just Nether and a misc helper plugin I'm writing,
