N-way runtime interoperative debugging

A method comprising:

• receiving by an n-way interoperative debug module executing on a processor, a debug communication from one of a plurality of runtime debuggees executing in a single debug process, the debug communication conforming to a protocol shared by the plurality of runtime debuggees, wherein the plurality of runtime debuggees comprise runtimes that do not execute debug code, detect transitions from one runtime debuggee to another runtime debuggee and detect exceptions thrown in other debugee runtimes;
• determining a current controlling runtime, comprising a runtime debuggee of the plurality of runtime debuggees by contacting in priority order at least one of the plurality of runtime debuggees;
• and
• notifying at least one of the plurality of runtime debuggees of the determined current controlling runtime.

A computer-readable storage medium comprising computer-executable instructions which when executed cause at least one processor of a computing device to:

• receive by an n-way interoperative debug module executing on the at least one processor, a debug communication from one of a plurality of runtime debuggees executing in a single debugee process, the debug communication conforming to a protocol shared by the plurality of runtime debuggees, wherein the plurality of runtime debuggees comprise runtimes that do not execute debug code, that detect transitions from one runtime debuggee to another runtime debuggee and that detect exceptions thrown in other debugee runtimes;
• determine a current controlling runtime, comprising a runtime debuggee of the plurality of runtime debuggees, by contacting in priority order at least one of the plurality of runtime debuggees;
• and
• notify at least one of the plurality of runtime debuggees of the determined current controlling runtime.
