My take after browsing through some of these external libraries is that
most people still use non-portable (but usually effective on common
platforms) manual padding hacks. I imagine that they do this so that
the code does not break on pre-jdk8. Given how this is turning out,
they will have no motivation to change what they do until jdk10 or so.
Sigh.
