NullPointerException thrown after stopping a script

[boomslap 5]

The following exception was thrown after I stopped a script I am developing. I tried rerunning the script and stopping it but it doesn't seem to recreate the error.

12:35:41 PM: [ERROR] Exception has occurred while running! Please report error to developer if problem persists:
	java.lang.NullPointerException: Cannot read the array length because "<local1>" is null
