#813 Lucene 5.2 does not work under WebStart

[Aaron Madlon-Kay]

Per [feature-requests:#1203], we are currently using a custom build of Lucene: lucene-core-5.2.1-SNAPSHOT.jar. Details from RFE:

• A few components within Lucene use features that are restricted when running under Java WebStart. This requires us to use a custom patched version.
  • Fork: https://github.com/amake/lucene-solr/tree/v5.2.1-webstart
  • Lucene bug: https://issues.apache.org/jira/browse/LUCENE-7135
  • LanguageTool bug: https://github.com/languagetool-org/languagetool/issues/378

When we are able to upgrade to a version of Lucene that is not affected by this issue, we should switch back to a standard build. This ticket should remain open until then.

Our custom build is published on Bintray/JCenter for consumption as a Maven-style dependency:
https://bintray.com/omegat-org/maven/lucene-core
compile 'org.omegat.lucene:lucene-core:5.2.1'

The bug has been fixed in Lucene 6 and 7, but is unlikely to be backported to 5, much less 5.2, so we will have to continue to maintain our fork until LanguageTool upgrades to 6 or later.

LanguageTool 3.9 uses Lucene 5.5.4, in which this issue is fixed. We can stop using our fork when we are able to update to LanguageTool 3.9 or later (see [#1299]).

We dropped WebStart
OmegaT 6.1 also updates dependency to Lucene 5.5.5 and LanguageTool 5.7.
