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

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.
