Re: [eclipse-dev] Do we still need ICU4J?

requires ICU 60.x 

It was done on
'org.eclipse.jdt.core.manipulation' only (no other bundle in the SDK defines
60.0.0 as minimal version) by Alex without a bug report that would describe
the need for that change.

jdt.lsused to use icu.base (58.2), but since https://github.com/eclipse/eclipse.jdt.ui/commit/3e36b6b6d9c0ea96d785c73f6950915cc8b5a402,
JDT requires ICU 60.x which has no base jar. That made jdt.lssize grow 25% overnight.

As has been said
before, those minimal apps can use ICU Base.

Dani, minimal RCP application is around 19MB of which ICU4J is around
13MB. So we are talking about ~70% size reduction for minimal RCP.

But with the new JVM cadence Java supports ICU4J pretty much at the same
time the JVM does. Keeping uptodate icu4j requires work in Orbit to get
it integrated (and used to be non-trivial but this is hopefully improved
now).

icu4j (master has 64.2 while latest is 65.1) we may even face a case where
using icu4j is holding off people that run on latest JVM from proper Unicode
support. Although, I don't believe that there is anything added in either
JVM or ICU4J that is of any practical use for us. Reading http://site.icu-project.org/home/why-use-icu4j most
of the reasons to use it are for pre Java 6.
