I got to test OS 10.7 today.  Some good news:

1.  I can still launch ImageJ in 32-bit mode if I want.
2. (dependent on 1.) I can still run plugins/classes that depend on
QTJava (32-bit only).
3.  Everything other than scrollbars seems pretty normal.

As Wayne mentioned, the scrollbars in Lion have lost their arrows in all
contexts, including Java and ImageJ windows.  There is no OS level
preference that allows you to bring them back.  This is clearly a pain
for any window with more than one scrollbar!  I wonder if that is a
different component that might substitute for awt.gui.Scrollbar and have
arrows?  It would be a minor pain to need to recode a
ij.gui.ScrollbarWithArrowsOnMacOS10_7.java just for this special case.  
Might be worth waiting on for Apple updates first, to see if they might
bring them back as an option.  There seems to be a certain amount of web
screaming going on already about the lack of the arrows on scrollbars in
general:

I also found this older command-line tip.  Might it give us some control
over the scrollbar arrows in 10.7?  I haven't tried yet.
defaults write "Apple Global Domain" AppleScrollBarVariant DoubleBoth
http://lifehacker.com/5040043/add-double-scroll-arrows-to-both-ends-of-the-scroll-bar

...although this option seems not to even work in 10.6.8...  so maybe
not much hope there in 10.7

Clearly it would help if the look-and-feel of Java on the Mac were not
so tied to the L&F of the OS itself.

This is not a problem with the channel/slice/frame scrollbars used with stacks and hyperstacks since they have keyboard shortcuts. It is a problem with other scrollbars, such as the ones in the "B&C" and "Threshold" windows, which currently lack keyboard shortcuts.
