P5 Description
The following section of the JDWP spec lists all supported EventKinds:
https://docs.oracle.com/javase/8/docs/platform/jpda/jdwp/jdwp-protocol.html#JDWP_EventKind
FRAME_POP, CLASS_LOAD, and EXCEPTION_CATCH are never used.
The only places where EventKind is mentioned generically (not in reference to a specific EventKind) is for EventRequest.Set and EventRequest.Clear:
https://docs.oracle.com/javase/8/docs/platform/jpda/jdwp/jdwp-protocol.html#JDWP_EventRequest_Set
https://docs.oracle.com/javase/8/docs/platform/jpda/jdwp/jdwp-protocol.html#JDWP_EventRequest_Clear
When events are enabled using EventRequest.Set, they are expected to arrive using the Event Command Set
https://docs.oracle.com/javase/8/docs/platform/jpda/jdwp/jdwp-protocol.html#JDWP_Event
It calls out all supported EventKinds, and the data that is expected in the packet for each EventKind that is supported. There is no mention of FRAME_POP, CLASS_LOAD, or EXCEPTION_CATCH, so the assumption is that these events are not supported and never delivered. Their references in the spec should be updated to "Never sent across JDWP"
