Oracle is changing the Java licensing for Java 8. After January 2019, commercial customers will only be entitled to such updates if they are paying Oracle for support.
Please see the Oracle Java SE Support Roadmap for more information on the end of public updates.
Note: For further information regarding Patch Management Solution and Java, see "Patching Java 8 after January 2019 changes"
Symantec Management Platform 8.1 and 8.5
ITMS 8.5 and 8.5 RU1 all have a dependency on Java 8.
The Management Platform help system in 8.5 RU2 now uses Java 11.
To migrate to Java 11, customers on the 8.5 and 8.5 RU1 versions should plan an upgrade to 8.5 RU2 or greater.
Please note that no Java license is bundled with the Symantec Management Platform or management suites. Java licenses should be obtained from Oracle
