usinng System.exit() still requires return... [message #257348]

Hi,

I noticed that eclipse does not detect that when I issue a System.exit(int)
call, any following code is unreachable, so if I stick it in a method with a
return type that isn't "void" it complains that my method is missing a return
statement.

Is this an option that can be user-set, or is it just a (for the moment)
shortcoming in the Eclipse java parser?

regards,

- Mike Kamermans

System.exit(int) is just another function call. The fact that it
terminates the VM is not something that is in any way relevant to the
parser. Every function is assumed to return regardless of what happens at
runtime, and so the flow of your code requires that all paths have
completed return statements.

This has nothing to do with Eclipse. System.exit() has no special
meaning in the JLS.
Try with javac and you will get the same result.
