Robert Muir resolved SOLR-2571.
-------------------------------
Resolution: Fixed
Committed revision 1132855 (trunk).
I organized the constants in DirectSolrSpellchecker a bit, so its easy to see
which ones are 'shared' with the others and which ones are unique to it.
Committed revision 1132856 (branch_3x).
I backported the test and example here. In the case of this test, it needed to
clearIndex() in setup() like trunk does, so I merged these bits also.
Thanks James!

>
> When parsing the configuration for thresholdTokenFrequency", the
> IndexBasedSpellChecker tries to pull a Float from the DataConfig.xml-derrived
> NamedList. However, this comes through as a String. Therefore, a
> ClassCastException is always thrown whenever this parameter is specified.
> The code ought to be doing "Float.parseFloat(...)" on the value.
> This looks like a nice feature to use in cases the data contains misspelled
> or rare words leading to spurious "correct" queries. I would have liked to
> have used this with a project we just completed however this bug prevented
> that. This issue came up recently in the User's mailing list so I am raising
> an issue now.
