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

Just to make sure - no I don‘t think one needs icu4j today in 99% of the cases but because it is on our API contracts the better option is to invest into icu-base

So who is going to do that? Any volunteers around?

You can not remove it eg eclipse-databinding has it baked into its API. Hence the only way forward is to make icu-base a valid artifact one can put on maven central.

Wow. Worry about 13MB. If so, they can use ICU Base.

There is no ICU Base it has been a weird artifact delivered only in Eclipse via a crippled build. As it's not on Maven central I claim that even ICU4J project doesn't consider this a viable option.
And this is not answering the question what do we need ICU4J nowadays?

Hi Alexander,

I have multiple RCP customers which would be happy if the 13MB could
be dropped from the platform.

+1 for getting rid of it.

Best regards, Lars

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.
