Forward declaration of classes needed when using GCJ?

[Andrew W]

Consider the following two classes placed in files 
./net/mydomain/core/ClassA.java and
./net/mydomain/core/ClassB.java respectively:

package net.mydomain.core;
public class ClassA
{

public static void main(String[] args) throws Exception
{
ClassB classb = new ClassB();
}

}


package net.mydomain.core;
public class ClassB
{


}

If I compile this using the 'normal' Java compiler like this:
javac ./net/mydomain/core/ClassA.java ./net/mydomain/core/ClassB.java

it works fine.

Using the GCJ command:

gcj --main=ClassA ./net/mydomain/core/ClassA.java 
./net/mydomain/core/ClassB.java

produces the error:

./net/mydomain/core/ClassA.java:8: error: Type ‘ClassB’ not found in the 
declaration of the local variable ‘classb’.
ClassB classb = new ClassB();

Under C++ you would use an include of the header file for ClassB and a 
forward declaration to solve this, whats the solution for Java classes 
under GCJ?

I should point out this is a compile-time syntax error not a linker 
error. Compiling ClassB separately and then passing it the .o file wont 
solve it. There needs to be some way of forward declaring ClassB inside 
ClassA.java.

Thanks
