1. A method for isolating execution of a plurality of applications in an object-oriented software environment, wherein a class in the object-oriented software environment comprises a static field, wherein the plurality of applications are configured to utilize the class, the method comprising:

  • programmatically generating a copy of the static field for each of the plurality of applications, thereby generating a plurality of corresponding copies of the static field, wherein each of the plurality of applications corresponds to a respective one of the corresponding copies of the static fields;

    programmatically deleting the static field from the class;

    programmatically generating one or more access methods for the corresponding copies of the static fields; and

    using the one or more access methods to permit one of the plurality of applications to access the respective one of the corresponding copies of the static fields.
