Managing static data structures of legacy software in dynamic class loader environments

A system for managing static data structures of a legacy data modeling software product in a dynamic class loader environment, wherein the dynamic class loader environment comprises a variable plurality of software bundles, and wherein the legacy data modeling software product is configured to use a registry associating external type identifiers with at least one data model class to create an in-memory representation of the at least one data model class, the system comprising:

• a hardware layer adapted for running an operating system that executes an execution system, the hardware layer comprising a processor in communication with a memory;
• and
• the execution system comprising:
• an initializer operable to identify an initial set of software bundles in the dynamic class loader environment, wherein the initial set of software bundles may comprise different versions of a specific software bundle;
• at least one bundle-specific registry constructed by the initializer, wherein a bundle-specific registry is constructed for each member of the initial set of software bundles, and wherein each bundle-specific registry associates at least one external type identifier with at least one data model class;
• a super-registry managing the at least one bundle-specific registry, wherein the super-registry replaces a default registry of the legacy data modeling software product, and wherein the super-registry provides the legacy data modeling software product with a constructed first bundle-specific registry corresponding to a first software bundle for use in creating the in-memory representation of the at least one data model class represented by an external type identifier associated with the first software bundle;
• and
• a listener configured to receive a notification that a new software bundle has entered the dynamic class loader environment, and further configured to construct a bundle-specific registry for the new software bundle upon receiving the notification.
