Jukka Zitting commented on JCR-352:
-----------------------------------
I tried changing the visibility of the difference() method, which did solve the
compile problem, but now I get a ClassCastException from
org.apache.lucene.store.Directory.createFile() when the repository is being
initialized. This problem can be reconstructed like this after placing
lucene/jars/lucene-1.9.1.jar in the local maven repository:
$ svn export
http://svn.apache.org/repos/asf/incubator/jackrabbit/branches/1.0/jackrabbit
$ cd jackrabbit
$ perl -i -pe 's/1.4.3/1.9.1/' project.xml
$ perl -i -pe 's/protected float difference/public float difference/' \
src/main/java/org/apache/jackrabbit/core/query/lucene/WildcardTermEnum.java
$ maven test
This seems to have something to do with the "this method should be abstract"
notice in the Lucene Directory.createOutput() method. The FSDirectory class in
Jackrabbit doesn't seem to play well with the modified Directory implementation
in Lucene 1.9.1.
If there is a similar simple and non-intrusive fix for this problem, then I can
have the change included in 1.0, otherwise not. In any case I am going to keep
Lucene 1.4.3 as the official dependency in Jackrabbit 1.0. A possible fix would
be there just to help people deploy Jackrabbit 1.0 with Lucene 1.9.1.
