CGLIB$SET_THREAD_CALLBACKS([Lorg.springframework.cglib.proxy.Callback) :

Question

Some Junit Test cases are failing when running all test classes together but passing individually.

**Caused by: java.lang.NoSuchMethodException: xxx.zzz$$SpringCGLIB$$0.CGLIB$SET_THREAD_CALLBACKS([Lorg.springframework.cglib.proxy.Callback;) ** at [email protected]/java.lang.Class.getDeclaredMethod(ExampleClass.java:2675) ~[data-feeder.exe:na] at org.springframework.cglib.proxy.Enhancer.getCallbacksSetter(Enhancer.java:901) ~[na:na] at org.springframework.cglib.proxy.Enhancer$EnhancerFactoryData.(Enhancer.java:490) ~[na:na] ... 40 common frames omitted

Any answer would be greatly appreciated!
