in Oot, do we want a base register to make addresses relative?

probably not; that's probably assumed/encapsulated away

ppl say that jsr/ret made the JVM verifier much more difficult to write. See [1], section The issue with JSR/RET. Why?

Maybe because ret jumps to an address in a register rather than to a fixed address?

Is jsr/ret the only computed goto in jvm?:

• no, there is also lookupswitch, but there you have a table of possible return values (and tableswitch, but that seems to be equivalent to JMP?)
• ret appears to be the only instruction in which it is not immediately obvious what all the possible jump destinations are (eg you could try things like jsr twice, then SWAP the return addresses, etc)
