My guess is this isn't a Solr issue at all; you are somehow using an old Java.
RBBIDataWrapper is from com.ibm.icu.text; I saw on a quick Google that this was cured by re-installing Eclipse, but that was from 5 years ago. You say your Java and IDE skills are a bit rusty, maybe you haven't updated your Java JDK or Eclipse in a while? I don't know if Eclipse somehow has its own Java (I haven't used Eclipse for quite a while). I take it this runs outside Eclipse OK? (well, with problems otherwise you wouldn't be stepping through it.....)
