All Implemented Interfaces:
Serializable

If something goes wrong while doing some scripting stuff, one of these is thrown. The integer code indicates what's wrong and the message may give more details. The reason one exception with multiple meanings (via the code) [instead of multiple exception types] is used is due to the interest to keep the run-time size small.
