How much CPU load is it using? It's not as good as a Cocoa app but jD really isn't that bad, I've never seen it use enough cycles to cause 88C temps. It's currently using 15% for me on MU, not enough to push my CPU past 65C.

it uses about 90-100% cpu accord to istatpro.

my MBP is the 15'' high end late 2008.
