5         * this by simply jumping to the handler.
6         *
7         * It's probably not necessary to update "inst", but we do it
8         * for the sake of anything that needs to do disambiguation in a
9         * common handler with INST_INST.
10         *
11         * The breakpoint itself is handled over in updateDebugger(),
12         * because we need to detect other events (method entry, single
13         * step) and report them in the same event packet, and we're not
14         * yet handling those through breakpoint instructions.  By the
15         * time we get here, the breakpoint has already been handled and
16         * the thread resumed.
