Method and apparatus for implementing concurrently running jobs on an extended virtual machine using different heaps managers

A virtual machine arranged to operate in cooperation with a computing system, the virtual machine including:

• a first mechanism for creating a first job and a second job which are respectively associated with a first application and a second application, the first job and the second job being arranged to concurrently run on the virtual machine;
• a second mechanism, the second mechanism being arranged to provide the at least one job with at least one class that is arranged to be shared between the first job and the second job;
• a third mechanism, the third mechanism being arranged to exchange information between the first job and the second job;
• wherein the virtual machine includes a jobs manager, a class manager, and a heap manager;
• wherein the jobs manager generates first and second jobs data, first and second garbage collection instance data, and virtual machine instance data respectively associated with said first and second jobs that concurrently run on the virtual machine, and the jobs manager further associates one or more methods to each of the jobs data, garbage collection instance data, and virtual machine instance data;
• and
• wherein the class manager is arranged to create proxy data which enables a class associated with the virtual machine to be shared by the first and second jobs that are arranged to concurrently run on the virtual machine.

A computer-implemented method for executing a first application substantially concurrently with a second application on a virtual machine, the computer-implemented method comprising:

• creating a first job on a virtual machine, the first job being associated with the first application;
• creating a second job on the virtual machine, the second job being associated with the second application;
• creating a first heap, the first heap being associated with the first job;
• and
• creating a second heap, the second heap being associated with the second job
• creating a jobs manager for concurrently supporting the first and second jobs on the virtual machine, wherein the jobs manager generates first and second jobs data, first and second garbage collection instance data, and virtual machine instance data respectively associated with said two or more jobs that concurrently run on the virtual machine, and the jobs manager further operating to associate one or more methods to each of the jobs data, garbage collection instance data, and virtual machine instance data;
• and
• creating a class manager which is arranged to create proxy data which enables a class associated with the virtual machine to be shared by the two or more jobs that are arranged to concurrently run on the virtual machine.

A computer readable medium including computer program code for executing a first application substantially concurrently with a second application on a virtual machine, the computer readable medium, comprising:

• computer program code for creating a first job on a virtual machine, the first job being associated with the first application;
• computer program code for creating a second job on the virtual machine, the second job being associated with the second application;
• computer program code for creating a first heap, the first heap being associated with the first job;
• and
• computer program code for creating a second heap, the second heap being associated with the second job
• computer program code for creating a jobs manager for concurrently supporting the first and second jobs on the virtual machine, wherein the jobs manager generates first and second jobs data, first and second garbage collection instance data, and virtual machine instance data respectively associated with said two or more jobs that concurrently run on the virtual machine, and the jobs manager further operating to associate one or more methods to each of the jobs data, garbage collection instance data, and virtual machine instance data;
• and
• computer program code for creating a class manager which is arranged to create proxy data which enables a class associated with the virtual machine to be shared by the two or more jobs that are arranged to concurrently run on the virtual machine.
