My understanding is that this will require Java 1.4. Is this correct? Is this because of changes to "core" functionality within Lucene or is it because some new additional classes require Java 1.4? If it's the latter then would it be possible to produce a custom build of Lucene that omits the classes that require Java 1.4? As you can probably guess from this that I have to support an older version of Java for certain platforms (Java 1.3.6). I don't know if I am unusual in this respect or if it is a common requirement. One of the new classes that I am using is the ConstantScoreQuery. I am not sure if this is going to be included in Lucene 1.9 or not but this does make use of Java 1.4. I have modified this to produce a version that works with pre 1.4 Java but probably at the expense of performance. I could submit this but if Lucene is going (has gone?) the 1.4 route there would be little point.
