public class MaybeRecoverableException
extends java.lang.Exception

Base class for exceptions that have an isRecoverable flag. If the flag is true, it means that the exception condition is probably not permanent and the caller is encouraged to retry the request, maybe after a short delay time. Examples for such reasons could be external resources that are currently not reachable, network problems and similar. Non-recoverable are invalid arguments, parse errors, external resources that really do not exists, etc.
