------------------------------------

             Summary: Upgrade ICU4J to newest version
                 Key: LUCENE-4665
                 URL: https://issues.apache.org/jira/browse/LUCENE-4665
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/analysis
    Affects Versions: 4.0
            Reporter: Shawn Heisey
             Fix For: 4.2, 5.0


Upgrade ICU4J to the latest version - 50.1.1 at the moment.

DictionaryBasedBreakIterator was eliminated by the upgrade, so some very small code changes were required.  All tests (including nightly and weekly) passed with patch.  I did not try running tests multiple times.  The branch_4x tests were run on Windows, where I run eclipse.  The trunk tests were run on Linux, the platform where I actually use Solr.

I have no idea whether the ICU tests are comprehensive enough to detect problems with version upgrades.

It is possible that I don't have enough knowledge to complete this upgrade properly.  I did my best.

A couple of javadocs mentioned the removed class.  I changed one (hopefully correctly), but didn't know what the other should say.
