jmap histogram and [C [B [D [F [I and [J

I've been using jmap to create the memory histogram for an application and I get output that lists [C, [B, [D, [F, [I and [J for some of the class names. I know that these are arrays of some type, possibly of primitives. Is there some explanation some place of what these types are?

I've downloaded the source for JDK 5 and searched through there but I had no luck. The language or JVM spec perhaps might have some explanation?

Any clues or direction on what these types are and where I can find a good explanation would be appreciated.

Thanks in advance.
