Heh, I'm a programmer. I have to admit though, that I very rarely check my return value for null after vars.get. I figure if my BSF sampler fails with a null pointer exception, I should know what's going on. Using "" + for string conversion is probably a little less efficient than Long.toString(variable), since you're creating some extra temporary strings that you'll have to garbage collect later on. It probably wouldn't make a measurable difference in your test, unless you looped through doing it a few thousand times or using a multi-megabyte String. A system I used to work on would store 30+ megabyte Strings on a regular basis. You definitely don't want to create any more copies of those than you have to!
