  • 1.  Error activating Agent Automic for Linux 24.4.0 with Java 25 and RedHat 9

    I installed it, and when I try to activate the agent, I get the following error:

    Hi Cesar,

    the Unix/Linux agent in v24 supports OpenJDK 17, but not version 25 (https://downloads.automic.com/tools/compatibility_matrix?compatibility-mode=component&offering_version_id=1763885151700&lifecycle_entity_id=1409143059253&component_id=1409143059262&version_id=1758689264624)

    Solutions (pick one)

    regards,
    Peter

    Hi Cesar,

    Java 25 will be supported with the 24.4.5 service pack.
