Mike Drob updated LUCENE-6993:
------------------------------
Attachment: LUCENE-6993.patch
Ok, making progress...
To recap what I've done so far (so that it's easier next time)
{noformat}
* ant gen-tlds
copy affected analyzers to a stdX directory
update affected factories
update jflex-legacy task in build.xml
update test data to use valid domains
* ANT_OPTS='-Xmx5g' ant jflex
* perl generateJavaUnicodeWordBreakTest.pl -v 8.0.0
* sed 's/6_3/8_0/g' TestStandardAnalyzer.java TestUAX29URLEmailTokenizer.java
{noformat}
(starred entries are verbatim commands)
I also had to add a special case to the perl script where if there is a double
quote inside of output string text to add a java escape. I saw this in one of
the other Unicode release notes relating to hebrew text. The specific test this
is necessary for is א"א
I was not able to figure out how to install jflex snapshot locally -- I thought
by running mvn install on master it would work but turns out I don't understand
the nuances of ivy. Consequentially, I have not updated the unicode directives
to 8.0 for any of the parsers, but all the analyzer/tokenizer tests still seem
to pass so we might be ok?

> We did this once before in LUCENE-5357, but it might be time to update the
> list of TLDs again. Comparing our old list with a new list indicates 800+ new
> domains, so it would be nice to include them.
> Also the JFlex tokenizer grammars should be upgraded to support Unicode 8.0.
