[OpenJDK 2D-Dev] Fwd: openjdk7 - use installed png and jpeg libraries

[Anthony Petrov]

(CC'ing awt-dev@ and 2d-dev@)

There's an RFE:

6565114: Allow using system copies of libjpeg, libpng and giflib for 
splashscreen
http://bugs.sun.com/view_bug.do?bug_id=6565114

I think that the scope of this RFE might be extended to support using 
system copies of the libraries for the core JDK as well, not only for 
the splashscreen.

However, the RFE is currently closed as a "Future Project" because the 
contributed patch contains some issues and the contributor was not 
available for a while. See the review thread for details (a link is in 
the Description of the bug).

In any case, if you plan to integrate such a change to OpenJDK 8, it 
should be reviewed here on the awt-dev@ and 2d-dev@ mailing lists.
