Really ? That is not something that was obvious to me ..

Ah .. you are also proposing to change the name of the file even when we
a system libjpeg. I thought you were proposing this only in the case
when an external
libjpeg was used so we don't load two .so's with the same name.
But I suppose the System.load would otherwise need to know what to do.
Whilst I can't think what problem this would cause also this hasn't
issue in the last 20 years. So we can try this .. but you'll need to
make sure you
catch all the APIs (inc splashscreen) that load this library.
