Subject [jira] [Commented] (JENA-177) If possible remove dependency to ICU4J by using Java built-in functionality
Date Mon, 02 Jan 2012 17:08:30 GMT


Andy Seaborne commented on JENA-177:

A clue, maybe.

When I tried upgrading from ICU4J 3.4.4 to any ICU4J that was newer during the release cycle,
some tests started failing on punycode.  So, it maybe that the replacements are right and
that we have dependency of old behaviour.

> Jena-core and IRI currently depend on ICU4J for implementing Unicode support. Since ICU4J
is rather heavyweight of which a rather small fraction is used, we should check if there is
a way of implementing the functionality in an alternative way, either by (i) using built-in
(standard) Java classes, (ii) other libraries that are already dependencies, or (iii) in a
completely alternative way. This is also supported by the fact that since relevant parts have
been initially implemented, Unicode support has been considerably extended in Java, see
