The expert witness for Oracle asserts that since the offset
is not itself a memory location, it is "symbolic".
:begin rant:
Of course this is nonsense. We're talking about a virtual
machine. Nothing in the instruction stream is ever an
actual memory location, nor is such a requirement consistent
with the ordinary meaning of "symbol".
A symbol is something that represents a thing (a person, an
object, a value, a process) while being distinct from that
thing.
The bytecode value here is the numeric offset. It
represents that value in the most literal way possible (a
binary integer that appears in the instruction format). The
fact that it is used as an offset (indirect address) rather
than in some other way to locate an item in memory does not
attest to a "symbolic" use.
