Let me quote this and put it in code tags so the columns line up and I can read it.

[edit] Argh, I can't, copy-pasting ruins the spacing and I can't even quote you to get it, it just vanishes completely because you put it in quote instead of code tags. Could you repost in code tags?

That 2396 in cache counts as free memory by the way, don't be alarmed because of the low count in 'free'.

Yes, Java is using 20% of available memory. The important column is RSS, for "resident set size", which only counts memory actually in RAM and physically in use.

Sometimes there's complications like lots of shared libraries artificially inflating the memory count(imagine a 10MB shared library used in 100 processes, which'd total a gig, even though it's using the same ten megs of physical RAM for all of them) but this isn't one of them.
