it looks as if the fileset/includes is *too wide in scope* and needs to be tightened a bit to specify one file at a time for pathconvert to operate on
<fileset dir="${gora.avsc.dir}" id="gora.avsc.files">
   <include name="**/*.avsc"/>
  </fileset>
<pathconvert property="avrofiles" refid="gora.avsc.files"/> should be tightened a bit to include just the /home/lewismc/ASF/2.x/src/gora/webpage.asvc
<fileset dir="/home/lewismc/ASF/2.x/src/gora" id="gora.asvc.files1">
 <include name="**/webpage.avsc"/> </fileset>
<pathconvert property="avrofiles" refid="gora.avsc.files1"/>
same goes with second file
<fileset dir="/home/lewismc/ASF/2.x/src/gora" id="gora.asvc.files2">
 <include name="**/host.avsc"/> </fileset>
<pathconvert property="avrofiles" refid="gora.avsc.files2"/>
pathconvert example that most closely emulates your task

<fileset dir="${src.dir}" id="src.files">
      
<include name="**/*.java"/>
    
</fileset>
  
    
<pathconvert pathsep="," property="javafiles" refid="src.files"/>

This example takes the set of files determined by the fileset (all files 
ending in .java), joins them together separated by commas, and places 
the resulting list into the property javafiles. 
The directory separator 
is not specified, so it defaults to the appropriate character for the current 
platform. 
leads me to believe that pathconvert task in this iteration is unable to distingush one directory from another
what would happen if you specify attribute <pathconvert dirsep=":" property="avrofiles" refid="gora.avsc.files"/>
