[Modification required] Synthetic method and Reflection Conflict

[wlsdnjs829]

issue
Starting from jacoco above version 0.8.7.
there is a problem with reflection due to the synthetic method ($jacocoInit) at ReflectionInstantiatorDefinitionFactory:175.
(param name - null)

If there are other places where synthetic methods are used,
it could cause issues, so filtering with the isSynthetic() method is necessary.
