Subject Problem due to making DocumentInputStream final in POI 3.5 beta
Date Thu, 12 Feb 2009 10:01:09 GMT


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


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?
