This class serves for finding out if a given JavaClass' ConstantPool references an Inner Class. The Java Virtual Machine Specification, Second Edition is not very precise about when an "InnerClasses" attribute has to appear. However, it states that there has to be exactly one InnerClasses attribute in the ClassFile structure if the constant pool of a class or interface refers to any class or interface "that is not a member of a package". Sun does not mean "member of the default package". In "Inner Classes Specification" they point out how a "bytecode name" is derived so one has to deduce what a class name of a class "that is not a member of a package" looks like: there is at least one character in the byte- code name that cannot be part of a legal Java Language Class name (and not equal to '/'). This assumption is wrong as the delimiter is '$' for which Character.isJavaIdentifierPart() == true. Hence, you really run into trouble if you have a toplevel class called "A$XXX" and another toplevel class called "A" with in inner class called "XXX". JustIce cannot repair this; please note that existing verifiers at this time even fail to detect missing InnerClasses attributes in pass 2.
