------------------------------------
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.
