This is not an ABCL bug.  Thanks to Olof-Joachim's instructions:

CL-USER> (jstatic "getProperty" "java.lang.System" "user.home")
"C:\\WINDOWS\\system32\\config\\systemprofile"

in accordance to the documentation.  I now need to figure out why Java and
ABCL think that "user.home" is
"C:\\WINDOWS\\system32\\config\\systemprofile".  It may be something in the
computer setup that was modified last week by our IT.

PS - I never thought it was a bug, but wanted to dig a bit deeper into my
JVM environment.
