Lucene42 about luke HOT 5 OPEN

I have the same problem not using ElasticSearch. I am using Lucene 4.3.0. When 
will Luke be updated to support Lucene 4.3?

Luke!!! Lucene 4.x, x>0, is waiting for you!!!

When opening an lucene index using lukeall-4.0.0-ALPHA.jar indexed through 
4.2.0 solr using  <luceneMatchVersion>LUCENE_42</luceneMatchVersion> I am 
receiving the following error : 

Invalid directory at the location, check console for more information. Last 
exception:
java.lang.IllegalArgumentException: A SPI class of type 
org.apache.lucene.codecs.Codec with name 'Lucene42' does not exist. You need to 
add the corresponding JAR file supporting this SPI to your classpath.The 
current classpath supports the following names: [Lucene40, Lucene3x, 
SimpleText, Appending]

Reproduced here as well! Even if I change the version to Version.LUCENE_40, I 
still keep getting:

Invalid directory at the location, check console for more information. Last 
exception:
java.lang.IllegalArgumentException: A SPI class of type 
org.apache.lucene.codecs.Codec with name 'Lucene42' does not exist. You need to

current classpath supports the following names: [Lucene40, Lucene3x, 
SimpleText, Appending]

Please, fix!

Furthermore, I have lucene-core:4.3.1:jar on my CLASSPATH.
