Javac (build 1.3.0-C (fcs)) compiles the source icls02001.java (see below) 
without complains but classfile for inner class IC of anonymous class overwrites 
classfile for local class IC. So execution of example fails with the message :

___ java -showversion -cp clss icls02001
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, interpreted mode)

Exception in thread "main" java.lang.NoSuchMethodError
	at icls02001.get(icls02001.java:18)
	at icls02001.main(icls02001.java:4)


Local class IC obtains full name icls02001$1$IC and the same name 
is constructed for second class IC because its outer class is anonymous 
and it in turn gets the name icls02001$1.

Oldjavac and compilers in previous jdk report errors on this valid source 
( see #4196251, closed now ).

New JCK (Tweety) test 

lang/ICLS/icls020/icls02001/icls02001.html

written after #4196251 will be excluded with the number of reported bug.
Note that icls02001.java doesn't contain names with '$' char so this case 
differs from the matter of #4302890 (Synopsis: declared/synthetic class 
name conflict undetected).
