Random failing test: TestIrishAnalyzer.TestRandomStrings

[paulirwin]

Is there an existing issue for this?

Describe the bug

There have been other TestRandomStrings failures, but this one seemed different enough in the error message and class under test to be its own issue, although this can be closed if it ends up being the same issue as the others.

ailed Lucene.Net.Analysis.Ga.TestIrishAnalyzer.TestRandomStrings [11 ms]
  Error Message:
   System.ArgumentOutOfRangeException : Specified argument was out of the range of valid values.
(Test: Lucene.Net.Analysis.Ga.TestIrishAnalyzer.TestRandomStrings)

To reproduce this test result:

Option 1:

 Apply the following assembly-level attributes:

[assembly: Lucene.Net.Util.RandomSeed("0xdc8f1b3b9e2e4df6:0x9ee184a962a602ed")]
[assembly: NUnit.Framework.SetCulture("ff-Latn-SL")]

Option 2:

 Use the following .runsettings file:

<RunSettings>
  <TestRunParameters>
    <Parameter name="tests:seed" value="0xdc8f1b3b9e2e4df6:0x9ee184a962a602ed" />
    <Parameter name="tests:culture" value="ff-Latn-SL" />
  </TestRunParameters>
</RunSettings>

Option 3:

 Create the following lucene.testsettings.json file somewhere between the test assembly and the root of your drive:

{
  "tests": {
     "seed": "0xdc8f1b3b9e2e4df6:0x9ee184a962a602ed",
     "culture": "ff-Latn-SL"
  }
}
