This is no doubt a step in the right direction but I wonder why then the
javapackager is broken since the release of Java 9 and nobody seems to care
although this problem has been known for more than half a year now.

Using the ‘jlink’ tool introduced with JDK 9 will make it even easier for application developers to package and deploy dedicated runtimes rather than relying on a pre-installed system JRE.  Oracle will begin transitioning from the standalone architecture later next year in what will be a multi-year effort.
