Cause

From the Java documentation, Java EE modules are deprecated in JDK9 and are going to be removed in the later versions.

Resolution

A Spectrum code change is required and Java 9 will be officially supported in the Spectrum 10.3.0 release. For any current GA release of Spectrum, Java 8 will need to be used.
