Subject Re: Cannot instantiate SPI class
Date Wed, 09 Jan 2013 06:20:15 GMT
Hmm, I don't know.

Are you actually using AppendingCodec?

For anybody else looking at this: the same exception is listed on <https://issues.apache.org/jira/browse/LUCENE-4391>
- see also linked issue <https://issues.apache.org/jira/browse/LUCENE-4440>.  Both of
these are marked as fixed in Lucene 4.0 though…

need to add the codec jars to Railo's classpath instead?  it doesn't make much sense to me
as they both should use the same class loader.
