Using the JRCMD, collected the JRockit Heap diagnostics data. Below is the output:

--------- Detailed Heap Statistics: ---------
69.5% 1240837k 316026 +1240837k [B
8.5% 133278k 1562216 +133278k [C

What does [B and [C stand for?

what process is occupying this much of memory? What is B and C?

    That's a good question.

    It's a user unfriendly way to say to byte and character arrays ;) It should be changed.

    From the VM spec:
    B byte
    C char
    D double
    F float
    I int
    J long
    L<classname>; reference an instance of class <classname>
    S short
    Z boolean
    [ one dimension array
