Possibly. I have no way of testing it, though. So will leave it to AIX
folk to have a look. My experience was that it isn't easily
reproducible. Some observations:

   1. Run swing app such as SwingSet2 on a headfull system. Since
      fontmanager will have a link dep on lawt_headless, and awt code
      loads libawt_xawt (headfull) on a headfull system, both libraries
      providing symbols needed by libfontmanager will be loaded. Then it
      depends whether this is a problem on that particular system or not.
      In my experience this worked on some systems and not on others.
   2. Solaris was build-time linking to libawt_headless causing bug
      8194870. So build-time linking got removed with that bug. Not sure
      why that bug is private :(

Thanks,
Severin
