Get the JDK source (per the OpenJDK instructions):

hg clone http://hg.openjdk.java.net/portola/portola
cd portola
bash ./get_source.sh

You need an existing Alpine with an already-built JDK. I have a Docker image of Alpine with glibc-based Zulu JDK:

tralamazza

module.exports = function(str) {
	var buf = Buffer(str.replace(/-/g, '+').replace(/_/g, '/'), 'base64');
	nodes = [];
	for (var i = 6; i < buf.length; i += 2)
		nodes.push(buf.readUInt16BE(i));
	return {
		version: buf.readInt32BE(0), // just a guess
		charClass: buf[4],
		_: buf[5], // what's this?
		nodes: nodes
