Robert Muir resolved LUCENE-7865.
---------------------------------
Resolution: Not A Problem
You need to run ant clean.
The constant value is 175, so AIOOBE with 170 is impossible unless your
compile/runtime icu versions don't match: your classes were compiled with an
older version.
This is also why it does not reproduce for me.
The constant is deprecated actually, because of this reason (since it grows
over time and runtime version may be different). We don't need to do anything
fancy about that, we just support the version we test against and thats it.
