This is a known issue. Anyway, thanks for reporting it! Please refer to
the following bug to track the status of the problem:
http://bugs.sun.com/view_bug.do?bug_id=6613927
Currently the bug is being fixed.
Concerning the possibility of using an external libpng library, we've
got the following bug report:
http://bugs.sun.com/view_bug.do?bug_id=6565114
However, we're postponing the fix because the submitter of the patch
haven't prepared a clean patch yet. The main reason to use a slightly
more comprehensive patch is to be able to use both the internal version
of the library and the external one (if the developer defines the
EXTERNAL_LIBPNG macro when building OpenJDK). It would be very helpful
if someone could provide a clean patch for the latter bug.

I found this thread talking about it:
http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2007-August/000192.html
So, I tried to modified the makefile to use the system png. It's very
roughly removing the integrated libpng and linking with png12.
Here is the patch:
https://www.jfrog.org/svn-jfrog/openjdk/patch/SplashScreen_libpng12.patch
Hope it helps.
