weird issue with solr and CentOS 5.7

[Boris Quiroz <bo...@menco.it>]

Hi all,

I'm facing a real weird issue here with solr (lucene 3.3) and CentOS
5.7. I've two servers, one running CentOS 5.5 and the other running
CentOS 5.7. Both servers has the same solr, java and tomcat versions,
the only difference between them is OS version.
I added a custom field to schema.xml: <field name="stream_isPrivate"
type="boolean" indexed="true" stored="true" required="false"/>. When
that type is boolean, on CentOS 5.5 works OK indexing Chinese
characters, but on CentOS 5.7 I got this exception:

INFO: [] webapp=/solr path=/select/
params={indent=on&start=0&q=我们从右上角讲起&rows=10&version=2.2} hits=1

That only happens on CentOS 5.7. I also tested on Ubuntu Server, and
also works OK.

solrconfig.xml and everything else is the same on both servers. Any
idea what could be happening? Should it be a CentOS bug?

Regards.
