          Priority: P2
            Bug ID: 53860
          Assignee: fop-dev@xmlgraphics.apache.org
           Summary: The pdf-transcoder jar created by fop 0.94 and later
                    includes classes from commons and avalon
          Severity: blocker
    Classification: Unclassified
                OS: All
          Reporter: djgraff209@gmail.com
          Hardware: All
            Status: NEW
           Version: all
         Component: pdf
           Product: Fop

The build for apache FOP produces a jar which includes partial subsets of
classes from commons-io, commons-logging, and avalon.

By doing this, it will potentially destabilize applications that are dependent
on these libraries.

Many web-application containers do not specifically enforce load order of jars
and as a result if the pdf-transcoder.jar from 0.94 (and whatever it is in
later releases) is loaded before the proper commons-io, commons-logging etc jar
files it will cause signature errors and other runtime errors to occur.

I discovered this while using the Eclipse BIRT Report Engine in a non-osgi
fashion within a web application.  My application logic utilizes a much newer
version of commons-io.

Please remove the "import" or "merging" of these class file subsets from the
build process and add a dependency on the full jars in question.

I think that this might not be a bug with FOP but with Eclipse BIRT.  I'll have
to circle with them and determine why the jar is included in the dependencies
of BIRT.  As it stands right now, there is a collision that is causing problems
when BIRT is deployed in a webapp using the maven dependencies for 3.7.2 (I
think) and I have to recheck the versions.

At this time, close this as won't fix.  If I can determine the issue on the
BIRT or possibly Batik side (which is also depended on by BIRT) I'll open a bug
where appropriate.

I think the reason these classes have been put in there is to allow the
transcoder JAR to be used as a stand-alone JAR. I could be wrong, but I don't
think the intention was for users to include it in the class path.

There are two JARs one with just the FOP specific classes and an all-in-one
version. Which one are you using?
