A method and apparatus for managing a run-time environment is provided for improving performance and scalability of networked computer systems. In one example of the invention, a method starts by loading a class file, the class file specifying a class that includes a static class variable and a static initializer to initialize the static class variable. The static initializer is then invoked to initialize the static class variable. The class and the initialized static class variable are then saved in a second class file. The second class file is then loaded into a shared memory, the second class file including the class and the initialized static class variable.

An invariant numeric reference format is defined in a run-time environment for both run-time and storage use. A numeric reference to an object encodes the location of the object as an integral offset from an implicit machine pointer. In environments where the size of contiguous virtual memory segments is limited, objects are stored in a number of fixed-size contiguous chunks in virtual memory called pages. A page-offset numeric reference includes an offset and a page number, which is used to index a page map that contains a page pointer to the beginning of the page. Page-offset numeric references are dereferenced by adding the offset in the numeric reference to the page pointer obtained from the page map based on the page number in the numeric reference.

A cushion-like, shock-absorbent insole for footwear comprises two vinyl sheets forming an airtight compartment and sealing therein one or more sheets of resilient foam. Vent holes arranged in at least one of the vinyl sheets, preferably at the heel and metatarsal areas, act as metering valves in conjunction with the inside surface of the shoe sole so that air trapped in the foam material cannot instantaneously escape and both cushioning and massaging are provided.

A heat insulation panel is adapted to be mounted in a window frame and includes a pair of spaced substantially flat face sheets connected by a plurality of connector strips extending therebetween. The peripheral edge of the panel is sealed by a gusset strip in air tight relation. The gusset strip has a firmer hand than the face sheets and is approximately 25% heavier in gauge so that upon inflation the edge of the panel remains substantially flat in order to form a broad substantially air tight seal with the periphery of a window frame in which the panel is inserted. The gusset edge also can cooperate with the edge of an adjacent panel to form a substantially air tight seal therebetween.

Techniques are provided for instantiating separate Java virtual machines for each session established by a server. Because each session has its own virtual machine, the Java programs executed by the server for each user connected to the server are insulated from the Java programs executed by the server for all other users connected to the server. The separate VM instances can be created and run, for example, in separate units of execution that are managed by the operating system of the platform on which the server is executing. For example, the separate VM instances may be executed either as separate processes, or using separate system threads. Because the units of execution used to run the separate VM instances are provided by the operating system, the operating system is able to ensure that the appropriate degree of insulation exists between the VM instances.

In one embodiment, a method for transferring digital files is provided. The method includes: downloading an application for facilitating the transfer of used digital files; storing the application at the client; receiving an indication of a used digital file that a user desires to sell; searching, using the application, storage on the client to determine any instances of the digital file; deleting any instances of the digital file if they are determined; transferring a forwarded file of the used digital file to a second entity; and deleting, using the application, the used digital file from the client upon transfer of the forwarded file.

A computer-implemented method and software are provided for supporting a platform independent object format for a run-time environment in which a definition of an object in terms of a composition of one or more primitive types and a platform-specific description of the one or more primitive types are accessed. A layout for the object is then generated in a high-order language based on the definition of the object and the platform-specific description.

A composition of a solution of a metal salt of a dioic acid that provides corrosion resistance and moisture resistance is disclosed for application to post-construction materials. The composition may further include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition for application directly to the surface of the post-construction material. The composition is effective for reducing corrosion of post-construction materials, including unreinforced concrete or reinforced concrete, and reduces the permeation of moisture and/or the extension of cracks/fissures within the post-construction material. The composition may be applied to the post-construction material through brush applications, spray applications, mist applications or the like.
