Compiler version "1.2beta4" (build JDK-1.2beta4-I)

Java compiler crashes while trying to compile next test.
This test also crash all previos compiler versions.
An example and compiler diagnostics follow:
-------------------------------------------------------
class arr00509 {
    Object a = new void[1];
}


> uname -a
SunOS novo35 5.5.1 Generic_103640-12 sun4m sparc SUNW,SPARCstation-20

> javac arr00509.java

-------------------------------------------------------

Therewith javac normaly compile bogus array creation expression type
of void[][]. This fact stay in contadictionary with JLS section 15.9 which state:
"... that is a new array whose elements are of the type specified by the PrimitiveType or TypeName."
The type void is neither PrimitiveType, nor TypeName JLS 4.2 & JLS 3.8
The VM throws an exception while trying to execute bytecode produced
by javac in this case.

An programm example and VM diagnostics follow:
-------------------------------------------------------
public class arr00510 {

    public static void main(String[] args) {
        Object a = new void[2][2];
    }
}

> uname -a
SunOS novo35 5.5.1 Generic_103640-12 sun4m sparc SUNW,SPARCstation-20
>javac arr00510.java
>
> java -version
java version "1.2beta4"
Classic VM (build JDK-1.2beta4-I, green threads, sunwjit)
> java arr00510
