System and method for minimizing inter-application interference among static synchronized methods

A method for isolating the execution of a plurality of applications, the method comprising:

• extracting zero or more static fields from an original class utilized by any of the plurality of applications, wherein the original class comprises at least one static synchronized method, and wherein each static synchronized method comprises an executable block;
• creating a static field class, wherein the static field class comprises zero or more instance fields corresponding to the zero or more static fields, and wherein each instance of the static field class corresponds to one of the plurality of applications;
• and
• replacing each static synchronized method with a corresponding static non-synchronized method, wherein the corresponding static non-synchronized method comprises the executable block from the corresponding static synchronized method which is synchronized on the corresponding instance of the static field class for the utilizing application.

A system for isolating the execution of a plurality of applications, the system comprising:

• an original class utilized by the plurality of applications, wherein the original class comprises zero or more static fields and one or more static synchronized methods, and wherein each of the static synchronized methods comprises an executable block;
• a modified original class generated from the original class, wherein the modified class comprises the original class without the static fields;
• a static field class generated from the original class, wherein each instance of the static field class corresponds to one of the plurality of applications, and wherein the static field class comprises zero or more instance fields corresponding to the zero or more static fields of the original class;
• and
• one or more static non-synchronized methods, wherein each static non-synchronized method is generated from a corresponding one of the static synchronized methods, and wherein each static non-synchronized method comprises the executable block from the corresponding static synchronized method which is synchronized on the corresponding instance of the static field class for the utilizing application.

A carrier medium comprising program instructions which are computer-executable to implement:

• extracting zero or more static fields from an original class utilized by any of a plurality of applications, wherein the original class comprises at least one static synchronized method, and wherein each static synchronized method comprises an executable block;
• creating a static field class, wherein the static field class comprises zero or more instance fields corresponding to the zero or more static fields, and wherein each instance of the static field class corresponds to one of the plurality of applications;
• and
• replacing each static synchronized method with a corresponding static non-synchronized method, wherein the corresponding static non-synchronized method comprises the executable block from the corresponding static synchronized method which is synchronized on the corresponding instance of the static field class for the utilizing application.
