routing, by the message router in accordance with an application-level message passing protocol, the application-level messages among the debug clients, the debug administrator, and the back-end debugger, including providing distributed control of the back-end debugger to the debug clients with application-level messages routed to the back-end debugger and routing the step over command to the back-end debugger;
performing, by the back-end debugger, the step over command, including ignoring the one or more events established by the requesting debug client and processing any other events encountered during performance of the step over command including performing, during execution of the step over command, events established by the other debug clients; and
returning, by the debug server to the debug clients in response to the application-level messages routed to the back-end debugger, client-specific debug results.

Abstract
In a distributed system that includes a debug server and debug clients coupled for data communications through a data communications network, where the debug server includes a debug administrator, a message router, a back-end debugger, and a debuggee, collaborative software debugging includes receiving application-level messages including receiving, from a requesting debug client, a step over command that includes an instruction to ignore, during the step over command, events established by the requesting debug client; routing the application-level messages among the debug clients, the debug administrator, and the back-end debugger, including providing distributed control of the back-end debugger and routing the step over command to the back-end debugger; performing the step over command, including ignoring the events established by the requesting debug client and processing any other events; and returning, to the debug clients in response to the application-level messages routed to the back-end debugger, client-specific debug results.
