The test:
vmTestbase/nsk/jdi/TypeComponent/isSynthetic/issynthetic002/TestDescription.java
has a nested class that accesses private fields of the enclosing instance and expects to see synthetic get/set methods added for each field. But with nestmates such accessors are no longer needed and so not generated.
The test needs to be updated to remove the failing checks, or convert to a different case that will generate synthetic methods, or else be removed altogether.
The test is ProblemListed by JDK-8010319
