* how the regression came into place: While I tried to
get xsmiles 0.5 running, I had problems with resource
loading code in Character.CharacterProperties. It used
the system methods of finding resources, that relied
on URLClassLoader to do the job. Unfortunately, since
users can specify URLStreamHandlers, and thus
introduce arbitrary code into the URL resolution
process, there were problems with code in user
supplied URLStreamHandlers trying to indirectly use
Character.CharacterProperties before it could be
initialized. My fix was to patch the resource loading
code in Character.CharacterProperties to operate
directly on the classpath without consulting
Unfortunately, I had not tested the code with bad
CLASSPATH settings, so the CLASSPATH examination loop
in my patch would bail out at the first bad entry,
instead of proceeding to look for the character tables
in other entries. Without loaded character tables
you'd observe interesting but silent crashes. I fixed
that one :) but did not commit an updated Klasses.jar
at the time. I'll outline my reasons for not updating
Klasses.jar in a separate mail.
I hope this mail answers the remaining questions about
the CharacterProperties regression. I know that my
patch for the issue described above is an ugly hack ;)
and I'd welcome a better solution.
