             Summary: Unexpected non-integer input in vault.sh causes error
                 Key: WFLY-2141
                 URL: https://issues.jboss.org/browse/WFLY-2141
             Project: WildFly
          Issue Type: Bug
          Components: Security
    Affects Versions: 8.0.0.Alpha4
            Reporter: Chao Wang
            Assignee: Chao Wang
            Priority: Minor


Execute bin/vault.sh, then input a non-integer parameter cause:
{noformat}
Exception in thread "main" java.util.InputMismatchException
	at java.util.Scanner.throwFor(Scanner.java:909)
	at java.util.Scanner.next(Scanner.java:1530)
	at java.util.Scanner.nextInt(Scanner.java:2160)
	at java.util.Scanner.nextInt(Scanner.java:2119)
	at org.jboss.as.security.vault.VaultTool.main(VaultTool.java:109)

	at org.jboss.modules.Module.run(Module.java:292)
	at org.jboss.modules.Main.main(Main.java:455)
{noformat}

Because VaultTool.main() only scans next token of the input as an int, better catch the InputMismatchException and exit peacefully as default action.
