System Requirements/Java 9

This feature is available starting from 3.0PR18Q1.

Additional Requirements

In addition to the common System Requirements, when working with Java 9, some components have extra requirements:

• Ant >= 1.9.4

Tomcat

• Default init scripts in 7.0.x and 8.0.x fail to start with Java 9 because they include java.endorsed.dirs system property which is no longer supported, init script can be edited to remove it, or use a newer Tomcat version. This is fixed in 8.5.x and 9.0.x.
• Being in 3.0PR18Q1 release, in CATALINA_OPTS it is necessary to include --add-modules=java.se.ee. This is no longer needed starting from 3.0PR18Q2.
