If a Discriminated union is defined with an unsigned discriminator, the java code generated by idlj compiler can not be compiled.

Try compiling the following idl code.

*******************
union FixedUnion switch(unsigned short)
{
case 0: short s;
case 1: long l;
default: boolean b;
};
*******************


javac gives the following error.

FixedUnion.java:80: Incompatible type for =. Can't convert null to short.
    __discriminator = null;
                    ^
1 error


Work around this problem is to remove unsigned from the union declaration.
