Changes from Java 9:

• JEP 286: Syntax: added local-variable type inference (var).
  • Style guidelines from Project Amber
  • FAQ from Project Amber
• Optional.get deprecated in favour of Optional.orElseThrow
• JEP 319: Provide a default set of root Certification Authority (CA) certificates in the JDK. (part of the OpenJDK convergence exercise).
• Version number system changed again.
• JDK-8177290: APIs for creating unmodifiable collections (probably replaces some stuff from Guava).
• JDK-8186535: removed some stuff from SecurityManager
• JDK-8148371: removed policytool
• JDK-8159544: removed things from com.sun.security.auth
• Improved Docker Container Integration probably means that at least some people will want to use Java 10 as an execution environment for the IdP.

• Copy factories for collections, optimising for already-unmodifiable structures. Makes the various "unmodifiable" collection wrappers mostly obsolete.
• Stream collectors for collections.
