Description Martin Oberhuber CLA 2009-09-28 17:49:46 EDT 
Mnemonics.java references com.ibm.icu.lang , which is not in the base package. As a result, ever RSE app needs to live with 5MB disk space baggage.

This may be a problem with icu.base -- it should expose the entire ICU API.
jem.util from WST also fails to load with icu.base.

See also bug 234245 comment 3 - "We should be able to run with the base plugin everywhere".
Comment 3 Martin Oberhuber CLA 2010-04-16 10:16:21 EDT 
Performance measurements on cold start (right after reboot) indicate that Eclipse 3.6m6 takes 38 seconds to load with ICU and 36 seconds with com.ibm.icu.base.

This is a 2 second or approx 5% performance loss, which we are not willing to take in our commercial product that will never be translated.

I have filed bug 309477 to ask the com.ibm.icu.base plugin to become a more complete replacement of the full ICU.
