/**
 * Cite: jdk1.1.8/docs/guide/innerclasses/spec/innerclasses.doc10.html: For the sake
 * of tools, there are some additional requirements on the naming of an inaccessible
 * class N. Its bytecode name must consist of the bytecode name of an enclosing class
 * (the immediately enclosing class, if it is a member), followed either by `$' and a
 * positive decimal numeral chosen by the compiler, or by `$' and the simple name of
 * N, or else by both (in that order). Moreover, the bytecode name of a block-local N
 * must consist of its enclosing package member T, the characters `$1$', and N, if the
 * resulting name would be unique./* w ww.  jav  a  2s  . co m*/
