Optimizing managed runtime applications for serverless environments

A computer system comprising:

• one or more computer processors;
• one or more computer-readable storage media;
• program instructions stored on the computer-readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• program instructions to receive method invocation statistics for a managed runtime application, wherein:
• the managed runtime application comprises code,
• the code comprises a plurality of classes,
• each class of the plurality of classes includes a corresponding bytecode for one or more methods associated with each class,
• the method invocation statistics identify at least one method of the one or more methods invoked during at least one previous execution of the managed runtime application;
• and
• program instructions to generate an optimized version of the managed runtime application based on the method invocation statistics by:
• retrieving the managed runtime application, and
• selectively replacing a first bytecode for the at least one method of a first class of the plurality of classes of the managed runtime application with proxy code based on the method invocation statistics, wherein the proxy code is configured for retrieving the first bytecode.
