Hybrid code modification in intermediate language for software application

A system for code modification in a bytecode language, comprising:

• a hardware processor;
• and
• memory storing one or more sequences of instructions which, when executed by the processor, cause the processor to carry out the steps of:
• modifying an execution engine of a programming language platform in the bytecode language when the execution engine is converted from source code into code in the bytecode language to alter a functionality of or add a new functionality to the programming language platform, wherein the modification of the execution engine is performed by at least one of a compiler and an interpreter;
• and
• modifying a software application in the bytecode language at runtime of the software application, wherein the software application is modified to include a runtime analysis rule that uses the altered or the added new functionality of the programming language platform, wherein the software application is modified by;
• i) after startup of the software application, loading a class of the software application into the execution engine;
• ii) inserting a first bytecode to methods of the loaded class based on the runtime analysis rule that uses the new functionality of the programming language platform;
• iii) after the class is loaded and the first bytecode is inserted into the methods of the loaded class, loading another class of the software application and repeating processes i)-iii) until all the classes of the software application are loaded and the first bytecode inserted into the classes.

A method for code modification in a bytecode language for a software application in a database system, comprising:

• adding a new functionality to an execution engine of a programming language platform after the execution engine is converted from source code into code in the bytecode language, wherein the new functionality is a string tracking function, a stream tracking function, or an array tracking function, wherein the modification of the execution engine by the adding is performed by at least one of a compiler and an interpreter;
• modifying a software application after the software application receives a request from a user system, wherein the software application is modified to include a runtime analysis rule that uses the added functionality of the programming language platform, wherein the software application is modified by;
• i) after startup of the software application, loading a class of the software application into the execution engine;
• ii) inserting a first bytecode to methods of the loaded class based on the runtime analysis rule that uses the new functionality of the programming language platform;
• iii) after the class is loaded and the first bytecode is inserted into the methods of the loaded class, loading another class of the software application and repeating processes i)-iii) until all the classes of the software application are loaded and the first bytecode inserted into the classes;
• and
• executing the modified software application on the modified execution engine with the new functionality to generate a hypertext transfer protocol (HTTP) response to the received request.
