I wasn't aware of this bug ID so thanks for that.  I think the final
solution needs to cover more than just splashscreen though, as there
are other uses of libjpeg elsewhere.

I don't know about this patch by the bug reporter.  The one in IcedTea
is pretty unusable upstream; it removes the in-tree libraries and
forces system libraries.  That's fine for distros, but for OpenJDK we
don't want to disrupt the status quo.  I've been meaning to look at
this for a while, but just haven't got round to it.  Maybe after the
next IcedTea7 release...
