It's not part of the spec, since the spec doesn't force the container to use any
particular pooling or caching technique.
And, in the case of Weblogic, it won't work, because I've found that the minimum
numbers of beans in cache can't be set to anything less than 8 (if it's set to
one, it won't be respected: the number will grow to 8). Don't ask me why.
