All Implemented Interfaces:
edu.umd.cs.findbugs.Detector, edu.umd.cs.findbugs.Priorities, org.apache.bcel.classfile.Visitor
public class PossibleUnsuspectedSerialization extends edu.umd.cs.findbugs.BytecodeScanningDetector
looks for serialization of non-static inner classes. As this serializes the enclosing class, it may unintentially bring in more to the serialization than is wanted
