Crash on 1.6.2?

[kcoop]

First of all, AWESOME plugin. I'm doing a class for young folks, and they're loving it.

That said, my server keeps crashing, and I think it's related to scriptcraft. Here's an example stack trace. This is running craftbukkit 1.6.2 (build 2879). Any thoughts?

Hi kcoop,

First of all, AWESOME plugin. I'm doing a class for young folks, and they're loving it.

Thanks for the comments :-)

That stack trace indicates a problem with one of the files which was loaded by ScriptCraft.
Have you changed any of the scripts (.js files) in ScriptCraft?
I'm guessing the 'classroom' module is being used but seems to be failing for some unknown reason.
I'm having trouble reproducing this issue but will do some more investigation later.
Thanks.

I haven't changed anything in the js files. I did create a directory containing a collection of .js files for each student, but they are empty, except one that invoked classroom.allowScripting(true) (which it turns out didn't work - maybe a loading order issue?).

What version of craftbukkit would you consider most stable for scriptcraft? I don't mind downgrading the server if that would help.

Here's a crash log from a more recent crash that looks completely different. Sadly I can't say what was being done, I think one of the students was experimenting. This appears recursive, some issue with blockCactus and setAir? Could this be some version incompatibility, or should I be restricting the students to particularly block types?

Hi,

I haven't been able to reproduce this problem with 1.6.4.

Can you send me the new student script and I'll see if I can reproduce it
with that file?

Are you using the beta 1.6.4 of CraftBukkit? We're using 1.6.2 release, thought it'd be more stable. :-) Would it be better to be using 1.6.4? Just looking for the most stable build for scriptcraft, don't need much else.

At this point they're still using /js, so I don't have a log (we'll be loading script files next week). Mostly they've been just been messing around with sphere and box (some of them fairly large, with lots of different block types).
