I think you're responding to the other branch of this thread!

What I was suggesting here is that Tim remove the regex code from the 
Lucene 1.4 codebase, since it requires Java 1.4, while everything else 
in Lucene requires only Java 1.2.

Separately, there's the issue of how Lucene should handle a bug in IBM's 
1.3 JIT, but that's not what I was talking about here.
