Uwe Schindler commented on SOLR-2504:
-------------------------------------

The line numbers in your stack trace do not correspond to the officially released version
3.1 of Lucene 3.1 / Solr 3.1. Maybe you have some older JAR files in your classpath?

> After migrating from 1.4 to 3.1 we experience the following behaviour:
> When SpellChecking is turned off, everything works fine.
> When Synonyms are *not* being used, everything works fine.
> When both, SpellChecking and Synonyms, are being used and a search is triggered, that
contains at least one of the words out of synonyms.txt the following error is thrown:
