Oracle is supporting Java 8 till 2030 as a paid binary if you download from them and free source code as part of the OpenJDK. Other OpenJDK vendors, like Adoptium, are providing free binaries till 2030 as well. Other folks may or may not provide free binaries. RHEL builds of the OpenJKD are free till November 2026, part of extended life support till 2030.

For us, the biggest driver for getting off Java 8 was SpringBoot dropping support for anything older than 17.
