Subject [jira] [Resolved] (LUCENE-4231) Lucene-test-framework has META-INF for Codec for PreFlexRWCodec but not instantiatable
Date Tue, 17 Jul 2012 21:04:34 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-4231?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir resolved LUCENE-4231.
---------------------------------

    Resolution: Not A Problem

This is all intentional.

PreFlexRW Codec is a (test-only) read-write version of Lucene3x codec to act like 3.x for
tests.

Its in the test-framework jar because its only for testing.

> The Lucene-test-framework for 4.0-ALPHA contains /META-INF/services/org.apache.lucene.codecs.Codec
which I didn't expect; shouldn't that only be in Lucene-core ?  Well its there, and it contains
org.apache.lucene.codecs.lucene3x.PreFlexRWCodec which is actually a class embedded in the
test framework jar file (again, unexpected).  However, this class depends on the existence
of Lucene3xCodec which is not part of this jar file.
> I discovered this because I accidentally had the lucene-test-framework 4.0-ALPHA on my
classpath along with the lucene-core 5.0 but Codec would fail at class initialization time
because the services failed to resolve.
