Abstract Method Delegation Flaw in Eclipse OpenJ9

CVE-2026-16441

What is CVE-2026-16441?

In Eclipse OpenJ9 versions up to 0.60, there exists a flaw when executing class files. If a previously concrete superclass method has been recompiled as abstract, the execution flow is incorrectly redirected to an interface default method. This unexpected behavior can lead to potential exploitation by allowing unintended access and execution of code through the interface, which could compromise the application's integrity.
