In another thread, it was pointed out that j2 stands for "Java to". As
in "Java to lcms". Anyway, I don't care about the particular naming
scheme here. Everything is foreign to me :)

Fantastic!

Yes, exactly.

If using the system libjpeg, this library would only contain JNI code. It
would call into the system libjpeg for actual libjpeg-related
functionality.

If using the bundled libjpeg, the bundled libjpeg code gets built and
included into libjavajpeg.so too. So both the stub JNI and libjpeg code
are included in this libjavajpeg.so.

Either way, there would be no libjpeg.so built. The JDK code will always
System.load("javajpeg") which would do the right thing. Does this make
sense?

Thanks,
Omair
