edu.umd.cs.findbugs.classfile.analysis	Classes of objects that are the result of executing an analysis engine on a class or method. The classes in this particular package are those that are independent of any particular bytecode-analysis framework (e.g., BCEL or ASM). Two important classes in this package are ClassData, which represents the raw data of a class, and ClassInfo, which represents symbolic information parsed from the class data.
edu.umd.cs.findbugs.classfile.engine.bcel	Support for analyses based on the BCEL bytecode framework.
