Abstract: In an email message method and system, an email server receives at least one user-defined constraint for a first email message, where the user-defined constraint comprises at least one of an expected format and expected content of a reply email message. The email server associates the at least one user-defined constraint with the first email message and sends the first email message to a recipient. In response to receiving the reply email message, the email server validates the reply email message against the at least one user-defined constraint.

Abstract: A system is provided which comprises multiple Java virtual machines (VMs). Each VM is capable of running a plurality of threads. The system includes at least one object which is shared between the VMs so that it is accessible from two or more VMs, and at least one non-shared object which is accessible only from a single VM. In order to perform a lock operation on a shared object, it is first detecting that an object is a shared object. In a preferred embodiment, this is accomplished by locating a predefined value in a particular lock data word in the object. In response to the detection, a monitor is used to control local access to the shared object for the thread that is requesting the object. The monitor is on the same VM as the requesting thread. In addition, a data structure, which may be a proxy object, is updated in order to associate the monitor with the shared object.
