What version of Java is bundled with version 6.5? Is it possible to upgrade the bundled instance of Java to a more recent version?
Version 6.5 comes bundled with Java version 1.8.0_72. There is no built-in functionality that allows for upgrading the bundled instance of Java. That said, versions 6.6 and later include a more recent version of Java.
There is a possible means of manually updating an agent's bundled instance of Java, but doing so is not best practice, as it is not officially supported and may render the system unstable. Details can be found under Additional Information below.
Refer to the following article for details on how to manually upgrade the instance of Java bundled with an agent installation: https://comm.support.ca.com/kb/Changing-JRE-version-for-Agents/KB000004500 (please note that doing so is at one's own risk).
