  • The following lines must be added in all headers of modified files for the Java™ 9 implementation:
 * This is an implementation of an early-draft specification developed under the Java
 * Community Process (JCP) and is made available for testing and evaluation purposes
 * only. The code is not compatible with any specification of the JCP.
  • Use @since 3.12 BETA_JAVA9 on all newly added members (same bundle version as in Neon).
