>            Priority: Minor

> When FSEdit encounters problems, it prints something and then exits.
> It would be better for any in-JVM deployments of FSEdit for these to be 
> raised in some other way (such as throwing an exception), rather than taking 
> down the whole JVM. That could be in JUnit tests, or it could be inside other 
> applications. Test runners and the like can intercept those System.exit() 
> calls with their own Security Manager -often turning the System.exit() 
> operation into an exception there and then. If FSEdit did that itself, it may 
> be easier to stay in control. 
> The current approach has some benefits -it can exit regardless of which 
> thread has encountered problems, but it is tricky to test.
