Question 2

Oracle JDK 27 is currently supported. End of life is scheduled for March 2027. Plan your migration before that date to avoid security risk.

Question 3

When does Oracle JDK 27 reach end of life?

Accepted Answer

Oracle JDK 27 reached (or will reach) end of life in March 2027. After this date, no security patches or bug fixes are issued by the vendor.

Question 4

What are the security risks of running Oracle JDK 27 after end of life?

Accepted Answer

After end of life, the vendor's standard support for Oracle JDK 27 ends, so newly discovered vulnerabilities may never be fixed unless a paid extended support option covers that version. Auditors ask about it too: PCI DSS requirement 12.3.4, for example, calls for a yearly review of vendor end-of-life announcements with a remediation plan approved by senior management.
