Disclosed are various embodiments for executing multiple applications in a single virtual machine. The classes of an application executing in the virtual machine are traversed to identify non-sharable static fields. Upon identifying a non-sharable static field, mapping data is created that corresponds to the non-sharable static field. During another traversal of the classes of the application, access to the identified non-sharable static field is translated into an access to the mapping data that is associated with the non-sharable static field.
