When a customer tries to execute twiddle to set a negative value for one of the attributes, it throws the exception.

For example when I try to set a Scheduler MBean InitialRepitions value to -1, it fails.

Command: twiddle set "jboss:service=Scheduler" "InitialRepetitions" "-1".

Possible problem might be, GetOpt class used in the org.jboss.console.twiddle.SetCommand Class is not accepting the -ve values.It consider the -ve numbers as

an invalid option.
