Exception

java.lang.IllegalStateException:

If the object is invalid, java.lang.IllegalStateException occurs. Note that this exception inherits from java.lang.RuntimeException and can therefore be compiled without being defined in catch or throws.

This exception occurs when both of the following conditions coexist:

• The subject that has this object is read-only.

• The logout process is performed using the logout method.
