Thanks Jonah
      
      I now can at least say the JRE inside a Feature is valid approach
      and still in use.  
      
      I can confirm the issue does occur in 0.25.0, not just
      0.26.0-SNAPSHOT.  I can also say that the error occurs with each
      of the four JRE Feature projects, not just the 
jre.linux.gtk.x86_64.Feature project.  
      
      I have added a typical 
pom.xml, 
feature.xml and 
build.properties
      files for additional background.  
      
      Creating a MCVE is no small task, the application stands a ~5,000
      files, and will require more time then I have.  Something that
      works 'live' is due in 7 days for a conference.  When the
      conference is over I can try then.  I was hoping to get this
      working for the conference.
