Hi,
I use MPXJ libraries for parsing MS Project files and Apache Tika libraries for parsing many other file formats in my application. Both the libraries rely on Apache POI jars for extracting text from MS Office files. The latest dev version of Tika has upgraded to POI 3.5 beta 4 but one of the classes in MPXJ libraries extends org.apache.poi.poifs.filesystem.DocumentInputStream (which is made final in POI 3.5 beta 4). This is throwing a NoSuchMethodError and causing my application to crash. Is there any workaround to avoid this error? Can the dev team make the class not final again or is there any specific reason for not allowing extension of this class? Thanks, Kumar
