Method and system for memory leak detection in an object-oriented environment during real-time trace processing

A process for profiling a program in a data processing system, the process comprising the computer-implemented steps of:

• allocating a first object during execution of a method;
• obtaining a reference to a profile data area associated with the method;
• updating object allocation metrics in the profile data area associated with the method;
• and
• storing, in the first object, the reference to the profile data area associated with the method.
