US Patent 11954514 Robotic process automation system with separate code loading

A robotic process automation system includes a server processor that performs an automation task to process a work item, by initiating a java virtual machine on a second device. A first user session that employs credentials of a first user for managing execution of the automation task is also initiated on the second device. The server processor loads into the java virtual machine, with a platform class loader, one or more modules, such as logging and security, that perform functions common to the sets of task processing instructions. A first class loader a first set of task processing instructions is also loaded. Then each instruction in the first set of task processing instructions is loaded with a separate class loader. The server processor causes execution, under control of the first user session, on the second device, the task processing instructions that correspond to the work item.
