Had an interesting error today:
...java.lang.IllegalArgumentException: UUID string too large
I was able to figure out that the tried and true troubleshooting and debugging method of "system.perspective.print()" was causing this error. I was trying to print out my input parameters and they... were too large for the print function.
Commenting out my print command resolved my issue.
I suppose one will just need to print portions of a largish array.
The rest of the stacktrace on that error would be interesting, if you've got it. That's certainly not a failure mode I would expect from printing a large array.
You could also try self.print(something), which goes through a slightly different mechanism. You don't get to control the output location, but it defaults to the same as system.perspective.print.
