Possible impacts:
org.eclipse.recommenders.injection 2.5.3.v20180609-1554 requires com.google.guava 15.0. Unsure if a newer version exists which works w/ Guava 21..
Not sure about the com.ibm.icu stuff -- is 62 compatible with 58?
The rest - the apache felix and ant stuff - should hopefully be fine.
As to Lucene removals:
* org.eclipse.recommenders.models 2.5.3 requires lucene.core 3.5
* o.e.epp.logging.aeri.feature requires lucene.analysis 6.1
* org.eclipse.datatools.sqltools.result (DTP) and org.eclipse.m2e.wtp.jpa.feature (WTP) both require org.apache.lucene.queryparser 6.1.0.v20161115-1612, which doesn't exist in 7.1 (Lucene loves to add and drop bundles will-nilly, don't they?)
So... either those bundles / features need updating to use lucene 7.1+ or else they'll have to build against old Orbit... and Simrel will end up having multiple versions of these IUs peppered in the mix.
What version of
HttpComponents are you thinking would be included/dropped? Currently I'm using httpcore 4.4.6 and httpclient 4.5.2, but I think I saw a thread about Platform moving to newer versions? cc: @Aleksandar Kurtakov Nick
