Re: Enhydra: PATCH: Enhydra Build On Windows, NT, Linux

Just a minor clarification for those interested in the
actual problem.

It shows up in the Jolt parser because it uses
Unicode character ranges.

The actual bug is not in JavaCC but in the
JDK.  The bug is in 1.1.7 and 1.2.
It is going to be fixed in the next JDK release.

The characters that cause the problem are \u018e
and \u0258.  These characters can not be included
in character ranges like "\u0100" - "\u01ff".  They
must be specified individually like
"\u0100" - "\u018d", "\u018e", "\u018f" - "\u01ff".

Anyway, that's probably more than you wanted to
know, but I just wanted people to be aware that it
is actually a JDK bug.
