[Geoserver-users] Upgrade to geoserver-2.5.2 leaves geoserver 'Unable to get reader' for MrSid files

I just attempted to upgrade from 2.4 to 2.5.2. I am running Geoserver in Tomcat 7 using JDK1.7 on a RedHat system (RHEL6). I am using GDAL (1.9.2), jp2k and ImageCollection plugins.

Geoserver 2.4 was working well, but the new version is generating a “org.geotools.data.DataSourceException: Unable to get a reader for the specified path” stacktrace for every access to a MrSid file.

Any ideas how to proceed?;
