Vendor Specific Command Set

Used to initialize communication between the Debug Agent (DA) and the KVM. The KVM determines if the DA is the correct one for this particular KVM. If so, then the KVM replies with a 32-bit bitfield that indicates any optional JDWP commands that the KVM is able to parse directly (meaning that the DA can pass these JDWP commands directly to the KVM without parsing/managing them). Whether out data or reply, if the ID string is the NULL string (its length is 0) then the receiver of the ID string ignores it.

Out Data

Reply Data

TABLE 43 – Structure of Out Data for Handshake Command
`String`	Identifier	Vendor specific ID string
`byte`	Major Version	The major version of the Debug Agent.
`Byte`	Minor Version	The minor version of the Debug Agent.

TABLE 44 – Structure of Reply Data for Handshake Command
`String`	Identifier	Vendor specific ID string.
int	Optional commands	32-bit bitfield that describes the optional JDWP commands that the KVM supports. This set of bits is in 'Network Order' (Big Endian) format.
Bit 0	VM Init event	KVM supports/sends `VM_INIT` event.
Bit 1	VM Death	KVM supports/sends `VM_DEATH` event
Bit 2	Method Entry Event	KVM supports/sends `METHOD_ENTRY` event
Bit 3	Method Exit Event	KVM supports/sends `METHOD_EXIT` event
Bit 4	Exception Event	KVM supports/sends `EXCEPTION` event
Bit 5	Exception Catch Event	KVM supports/sends `EXCEPTION_CATCH` event
Bit 6	Class Load Event	KVM supports/sends `CLASS_LOAD` event
Bit 7	Class unload Event	KVM supports/sends `CLASS_UNLOAD` event
Bit 8	Single Step Event	KVM supports/sends `SINGLE_STEP` event
Bit 9	Thread start Event	KVM supports/sends `THREAD_START` event
Bit 10	Thread death Event	KVM supports/sends `THREAD_DEATH` event
Bit 11	Frame pop Event	KVM supports/sends `FRAME_POP` event
Bit 12	Field Access Event	KVM supports/sends `FIELD_ACCESS` event
Bit 13	Field modification Event	KVM supports/sends `FIELD_MODIFICATION` event
Bit 14	Event management	If set then the KVM keeps a list of events that have been set by the debugger and does not need the debug agent to return the breakpoint opcode after a breakpoint event.
