--- Comment #2 from Curtis Rueden <ctrueden at wisc.edu> ---
The bug is caused by a javassist problem:

IJ_PREFS_DIR=/Users/curtis/fiji
/Applications/Science/Fiji.app/Contents/MacOS/ImageJ-macosx
Jul 17 10:03:33 sirius ImageJ-macosx[13910] <Error>: The function
`CGContextErase' is obsolete and will be removed in an upcoming update.
Unfortunately, this application, or a library it uses, is using this obsolete
function, and is thereby contributing to an overall degradation of system
performance.
java.lang.IllegalArgumentException: Cannot override field access to prefsDir in
ij.Prefs's public java.lang.String load(java.lang.Object ij, java.applet.Applet
applet)
