I'm pretty sure the problem is with how you are calling `jdb.receiveReplyFor("2 2 " + JdbCommand.up)`. `receiveReplyFor()` is only going to wait for 1 prompt to be returned. I think usually they are all returned together, so usually you get all 4 prompts, but sometimes they get split up. The way to fix this is to use `jdb.receiveReplyFor("2 2 " + JdbCommand.up, true, 4)` since you want to wait for 4 prompts.
