Abstract

Resolving segmented constant pools in a virtual machine managed runtime. An embodiment includes allocating, using one or more processors of a computing device, for each specialization created in a class of specializations, a constant pool (CP) cache, assigning an owner to each segment of constant pools, maintaining, in a memory of the computing device, a list of specializations in the class, and copying, upon determining that a CP segment entry visible to the specialization is resolved in the owner, the entry to a specializations cache of the memory. An embodiment includes assigning a new specialized CP segment as an owner of that CP segment and adding a new entry associated with the new specialization to a template class owners table, retrieving, based on looking for entry at runtime, a slot pointed to in the owners table and resolving the CP entry in the constant pool cache of the owner.
