Public bug reported:

***** problem is caused by a Java implementation limit:

A compiled class file cannot be larger than 64 KB.

Since internally when running a script, this is compiled into a class
file, and might be too large.

I will try to find some assistance help for a scripter, to know, when
his stuff is too large.

So you have to divide your script into smaller packages and use import

I wrote a 500 line sikuli script to play baccarat on an online casino.
The script was working fine so I decided to add some conditional statements to handle specific events in the game.
I added an additional 2500 lines of code and when I run it I get the following error - what does it mean ?

[error] script [ casino.com] stopped with error at line --unknown--
[error] Could not evaluate error source nor reason. Analyze StackTrace!
