Copy code
val bolCache: MutableMap<String, SoftReference<Pai2<RowVec, String>>> = WeakHashMap(0)t

Not sure what you're doing, but looks really scary. There's a a lot of possible issues.

it gets the job done, and exploits the one thing softref does well, holds garbage for a little while
elvis1, elvis2, and elvis3 all need to agree that the row is !null or the map follows through with getOrPut (again)
