WARNING: if you change StandardTokenizerImpl.jflex and need to regenerate
the tokenizer, only use Java 1.4 !!!
This grammar currently uses constructs (eg :digit:, :letter:) whose
meaning can vary according to the JRE used to run jflex. See
https://issues.apache.org/jira/browse/LUCENE-1126 for details.
For current backwards compatibility it is needed to support
only Java 1.4 - this will change in Lucene 3.1.
