JDK 9 cannot generate or parse class files compiled with -target 1.5 [1].
Per the JPMS Armistice talks, "Automatic-Module-Name" header should only
be added to jars that have been tested under JDK 9 [2].
Also, javac now supports the new "--release" argument as an alternative to
source + target.
Roughly speaking, this option combines -source & -target with a little bit
of animal sniffing. JDK 9 includes signatures for JDK 6,7,8, and 9 (i.e.
all the releases which jdk9 can compile for).
This option is supported by maven-compiler-plugin [4] via a <release>
element in the plugin configuration, or by settting the property
*maven.compiler.release* .
