Compiler doesn't create class file for inner class, declared inside of
another inner class, which, in turn, is declared within a block. Doing so,
it does not report any errors and succeeds in compilation. As a result of
this, JVM throws java.lang.NoClassDefFoundError exception during execution
of such a program.

Example 'Test.java' demonstrates this behaviour. After successful
compilation of 'Test.java', we have the following classes in output
directory:
Test$1$A.class
Test.class

As we try to run the program, java interpreter says (see console output
below):
java.lang.NoClassDefFoundError: Test$1$A$B
at java.lang.Thread.init(Thread.java)

Note, that all compilers from JDK1.1_Final thru JDK1.1.3B produce no
class file for class Test$1$A$B that way.


--------------------Test.java----------------------
public class Test {
public static void main(String argv[]) {
class A {
class B {}
}
new A().new B();
}
}
