Abstract

Claims (73)

1. A tangible, non-transitory computer-accessible storage medium storing program instructions executable by one or more processors to:

analyze virtual machine bytecode of a software application to detect access by the bytecode to a native code module, wherein the software application includes at least one object-oriented class;

wherein to detect access by the bytecode to the native code module, the at least one object-oriented class is analyzed responsive to the at least one object-oriented class being loading during execution of the software application;

in response to said detecting the access by the bytecode to the native code module, automatically modify the bytecode by adding additional bytecode to the software application, wherein the additional bytecode is executable to automatically modify the native code module by adding additional native code to the native code module, wherein the additional native code is executable to determine information regarding execution of the native code module during execution of the software application.

2. The computer-accessible storage medium of claim 1 ,

wherein the additional bytecode is executable to invoke a software tool that performs the automatic modification of the native code module.

3. The computer-accessible storage medium of claim 1 ,

wherein the program instructions are further executable by the one or more processors to execute the additional bytecode during execution of the software application, wherein the additional bytecode executes to add the additional native code to the native code module.

4. The computer-accessible storage medium of claim 3 ,

wherein executing the additional bytecode comprises executing the additional bytecode on a virtual machine.

5. The computer-accessible storage medium of claim 1 ,

wherein the program instructions are executable by the one or more processors to add the additional bytecode to the software application during execution of the software application.

6. The computer-accessible storage medium of claim 1 ,

wherein the program instructions are executable by the one or more processors to add the additional bytecode to the software application prior to execution of the software application.

7. The computer-accessible storage medium of claim 1 ,

wherein the software application includes bytecode implementing a first method;

wherein automatically adding the additional bytecode to the software application comprises automatically inserting at least a portion of the additional bytecode into the bytecode implementing the first method.

8. The computer-accessible storage medium of claim 1 ,

wherein the native code module comprises one or more of:

a native code library;

a native code software component;

a native code method;

a native code function.

9. The computer-accessible storage medium of claim 1 ,

wherein detecting the access to the native code module comprises one or more of:

detecting loading of a native code library;

detecting invocation of a native code routine.

10. The computer-accessible storage medium of claim 1 ,

wherein the additional native code is executable to determine one or more of:

profiling information for the native code module;

debugging information for the native code module;

tracing information for the native code module;

monitoring information for the native code module;

instrumentation information for the native code module;

information regarding a programmatic call performed by the native code module;

a parameter value passed in a programmatic call performed by the native code module.

11. The computer-accessible storage medium of claim 1 ,

wherein the additional native code is executable to determine one or more of:

timing information for the native code module;

invocation count information for the native code module;

performance information for the native code module;

memory usage information for the native code module;

resource usage information for the native code module;

network usage information for the native code module;

database access information for the native code module;

data used in the native code module.

12. The computer-accessible storage medium of claim 1 ,

wherein the program instructions are further executable to execute the modified native code module, wherein the additional native code added to the native code module executes to determine the information regarding the execution of the native code module.

13. The computer-accessible storage medium of claim 12 , wherein the program instructions are further executable by the one or more processors to:

display on a display device the information determined by the additional native code added to the native code module.

14. The computer-accessible storage medium of claim 1 , wherein the program instructions are further executable by the one or more processors to:

cache the modified native code module.

15. The computer-accessible storage medium of claim 1 ,

wherein the virtual machine bytecode of the software application comprises bytecode for a Java Virtual Machine (JVM).

16. The computer-accessible storage medium of claim 1 ,

wherein the virtual machine bytecode of the software application comprises bytecode for a Common Language Runtime (CLR) virtual machine.

17. A system comprising:

one or more processors; and

memory storing program instructions;

wherein the program instructions are executable by the one or more processors to:

analyze virtual machine bytecode of a software application to detect access by the bytecode to a native code module, wherein the software application includes at least one object-oriented class;

wherein to detect access by the bytecode to the native code module, the at least one object-oriented class is analyzed responsive to the at least one object-oriented class being loading during execution of the software application;

in response to said detecting the access by the bytecode to the native code module, automatically modify the bytecode by adding additional bytecode to the software application, wherein the additional bytecode is executable to automatically modify the native code module; and

execute the software application, wherein in executing the software application the program instructions are executable by the one or more processors to:

execute the additional bytecode added to the software application, wherein the additional bytecode executes to automatically modify the native code module by adding additional native code to the native code module, wherein the additional native code is executable to determine information regarding execution of the native code module; and

execute the modified native code module.

18. A method comprising:

a computer system analyzing virtual machine bytecode of a software application to detect access by the bytecode to a native code module, wherein the software application includes at least one object-oriented class;

wherein to detect access by the bytecode to the native code module, the at least one object-oriented class is analyzed responsive to the at least one object-oriented class being loading during execution of the software application;

in response to said detecting the access by the bytecode to the native code module, the computer system automatically modifying the bytecode by adding additional bytecode to the software application, wherein the additional bytecode is executable to automatically modify the native code module; and

the computer system executing the software application, wherein said executing the software application comprises:

executing the additional bytecode added to the software application, wherein the additional bytecode executes to automatically modify the native code module by adding additional native code to the native code module, wherein the additional native code is executable to determine information regarding execution of the native code module; and

executing the modified native code module.
