Bytecode can be modified to adjust a returned address associated with a target function according to some examples. In one such example, a system can analyze bytecode to identify a location of a first bytecode segment that is intended to return an address for a target function. The system can then modify the bytecode to replace the first bytecode segment with a second bytecode segment at the location. The second bytecode segment can be configured to call a supplemental function that is executable to return the address for the target function.

Modifying bytecode to return an address associated with a target function

A system includes a processor in communication with a memory, a virtual machine running on the processor, and an application executing within the virtual machine. The virtual machine is associated with at least one testing tool configured to transform a plurality of application classes of the application, such that each respective class of the plurality of application classes is configured to track its respective usage. The testing tool is further configured to test the application with a plurality of tests, and while testing the application, map which respective classes of the plurality of application classes are used by respective tests. Additionally, the testing tool is configured to determine which class(es) is used by which tests (e.g., a subset of tests). Responsive to a first class being modified, the testing tool is configured to retest the application with the subset of tests.
