Brendan Robert has released an update to JACE, a Java-based Apple II emulator.  Here’s a list of the latest changes, per his comp.sys.apple2 post:

Changes since last build:
-Better NTSC color emulation
-Fixes to prevent crashes on start (race condition in video initalization)
-Tweaks to sound timing
-Experimental raw sound output (activate/deactivate with F7)
-Help text on start screen now reports correct key shortcuts
-Lots of other things here and there I’ve forgotten about (it’s been a while!)
-Removed some configuration options that were causing unnecessary grief (Program counter shouldn’t be a config variable)
