[Bug classpath/43049] New: ClassCastException when trying to serialize enum arrays

[lorban at bitronix dot be]

Take any simple enum, for instance:

enum MyEnum {
    A, B, C
}

then create an array of them:

Object o = new MyEnum[] {MyEnum.A, MyEnum.B, MyEnum.C};

then try to serialize it with an ObjectOutputStream:

ObjectOutputStream oos = new ObjectOutputStream(out);
oos.writeObject(o);

the oos.writeObject(o) line will then throw this exception:

Exception in thread "main" java.lang.ClassCastException: [Lmain/MyEnum;
   at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:332)
   at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:186)
   at ( the oos.writeObject(o) line )
