Post by: Phisk on December 16, 2014, 04:07:05 PM
What does this alert mean and why does it show up? Thanks for your help!

arrays are used in programming language. Could be you need to update Java (by Oracle media) or are you using a JavaScript yourself?

Arrays have an index and like the error says and could be anything but usually it's because the script is missing a semi-colon somewhere.

Hi Phisk,

a) Is this happening when the application starts up or when you're doing something in particular?

b) is there an error.log in the JCloisterZone directory?

c) Can you confirm what version of Java you are running?

d) Can you confirm JCloisterZone is the latest version 3.0.2?

Cheers :)

Hi Decar,

a) I placed a tile and suddenly this showed up.

b) yes there is.

c) Unfortunately I'm not very experienced with computers so I don't know :-\

d) Yes, it's the latest version.

Thanks

That's useful,

Does it happen every time you place a tile or was it a one off?

Any chance you can paste the content of the error.log here - it might contain a clue.

I'm trying to find an easy way of checking your java version - it's probably 1.7 so I imagine that's not the cause.

You might be able to check you're up to date with this:

Hi
In help menu is choice to create bug report (which contains java version etc). So if it happens again plese try to create report.

Ok, it says I have the recommended Java version installed.

It happened when I placed a single tile. I started a new game today and there were no problems at all.

the error.log says:

FYI:
A few days ago I took part in a 3-player game where the Bridges, castles and bazaars expansion was included.
When there was only 2 tiles left in the stack, one of us drew the remaining Bazaar tile, and then it happened: the "ArrayIndexOutOfBoundsException" appeared.
So apparently the problem occurs when there is less tiles left than the number of players.

According to CAR, in such a situation the Bazaar has to be ignored so that would be the appropriate behaviour of JCZ.

That's it, exactly.
Fortunately the last two tiles of that game could not influence the final result yet, everything was already decided by that time.
