initialization of static arrays

[m.morel]

Hello,

I would like to generate a class with a static field which is an array :

CtClass generatedClass = pool.makeClass("TestClass");
CtField myStaticField = new CtField(pool.get(MyClass[].class.getComponentType().getName()), "myStaticField", generatedClass);
myStaticField.setModifiers(Modifier.STATIC);
generatedClass.addField(myStaticField);

I want to initialize the array when loading the class (in a static block):

CtConstructor classInitializer = generatedClass.makeClassInitializer();
String classInitializerBody = "{\n";
classInitializerBody += ("myStaticField = new MyClass[2];\n");
classInitializerBody += ("\n}");
classInitializer.setBody(classInitializerBody);

Unfortunately, I get the following error :

javassist.CannotCompileException: [source error] incompatible type for =
 at javassist.CtBehavior.setBody(CtBehavior.java:194)
 at javassist.CtBehavior.setBody(CtBehavior.java:163)
 at javassist.CtConstructor.setBody(CtConstructor.java:201)
 at test.Main.main(Main.java:41)

It seems that I get this error for any type of table, including tables on classes from the jdk, except for Object[].

My question is : is it impossible to initialize static arrays in static blocks with Javassist? Am I doing it the wrong way? Is there a walkaround?

Thanks for any help,

CtClass generatedClass = pool.makeClass("TestClass");
CtField myStaticField = new CtField(pool.get(MyClass[].class.getComponentType().getName()), "myStaticField", generatedClass);
myStaticField.setModifiers(Modifier.STATIC);
generatedClass.addField(myStaticField);

The third line is wrong. It should be:

CtField myStaticField = new CtField(pool.get("MyClass[]"), "myStaticField", generatedClass);

In the original code, the type of the added field is not MyClass[] but MyClass.
