Creating TypeDescryption of Array in ByteBuddy - byte-buddy

Question

I want to create classes like this in Byte-Buddy:
class A{
public B b;
}
class B{
public A[] a_array;
}
this is my code on how I imagine it could be done:
InstrumentedType arrayType = InstrumentedType.Default.of("[A",
TypeDescription.Generic.Builder.rawType(Object.class).build(),
Modifier.PUBLIC);
DynamicType.Unloaded B_made = new ByteBuddy()
.subclass(Object.class)
.name("B")
.defineField("a_array", arrayType, Modifier.PUBLIC)
.make();
DynamicType.Unloaded A_made = new ByteBuddy()
.subclass(Object.class)
.name("A")
.defineField("b", B_made.getTypeDescription(), Modifier.PUBLIC).make();
Class A = A_made.include(B_made).load(Test.class.getClassLoader()).getLoaded();
Class B = A.getField("b").getType();
System.out.println(B.getField("a_array"));
But this does not work even though Byte-Buddy will make the classes and load the them.
This code gives me this when evaluating B.getField("a_array")
Exception in thread "main" java.lang.NoClassDefFoundError: L[A;

... 5 more
I was wondering how can I fix this?
is it even possible for me to create TypeDescription of [A from TypeDescription of A??

Answer 1

To construct an array type, use TypeDescription.Generic.Builder which allows for creating array representations. Do not use InstrumentedType.Default for creating arrays as they are intended to represent definable types.
