1. A method for enforcing consistent states for bootstrap class loader-defined classes across at least two concurrently executing, separate applications attached to a first defined memory region, the method comprising: establishing an association between the first defined memory region and a first list of attached applications, wherein each one of the applications in the first list of attached applications is a concurrently executing, separate application that is attached to the first defined memory region; establishing an association between the first defined memory region and a first list of loaded dependent bootstrap class loader-defined classes, wherein each application in the first list of attached applications for the first defined memory region is required to maintain consistent states for each class in the first list of loaded dependent bootstrap class loader-defined classes; in response to a first application attempting to attach to the first defined memory region: sending, to the first application, the first list of loaded dependent bootstrap class loader-defined classes; selecting, by the first application from the first list of loaded dependent bootstrap class loader-defined classes, a first class that has not been initialized by the first application; initializing, by the first application, the first class; and adding, after the first class is initialized, the first application to the first list of attached applications.
