Sharing applications in a java virtual machine

摘要

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.

主权项

1. A non-transitory computer-readable medium embodying a program executable in at least one computing device, wherein, when executed, the program causes the at least one computing device to at least:
conduct a first traversal of a class loader dependency graph corresponding to a plurality of classes of an application; during the first traversal of the class loader dependency graph,
identify a non-sharable static field within the plurality of classes; andcreate mapping data for the application in response to identifying the non-sharable static field, the mapping data including data corresponding to an instance of the non-sharable static field; conduct a second traversal of the class loader dependency graph corresponding to the plurality of classes following completion of the first traversal; and translate, during the second traversal, an access to the non-sharable static field within the plurality of classes into a translated access to the instance of the non-sharable static field in the mapping data.
