Compiler version "1.2beta4" (build JDK-1.2beta4-K, green threads, sunwjit)

Java compiler crashes while trying to compile next test.
This test also crashes all 1.2beta4 compiler versions,
but bug is absent in 12.beta3.
An example and compiler diagnostics follow:
-------------------------------------------------------
public class B {

   public static void main(String argv[]) {
      switch( 0 ){
       case 0/0:
      }
   }
}

> uname -a
SunOS novo35 5.5.1 Generic_103640-12 sun4m sparc SUNW,SPARCstation-20
> javac B.java
