  "details" : [ "In Eclipse OpenJ9 versions up to 0.60, when executing class files where a previously concrete superclass method has been recompiled as abstract, execution is incorrectly delegated to an interface default method.", "A flaw was found in Eclipse OpenJ9. When executing specially crafted class files, the Java Virtual Machine (JVM) incorrectly delegates method calls from a recompiled abstract superclass method to an interface default method. This can lead to unexpected program behavior and potential data integrity issues." ],
