javassist.CannotCompileException: [source error] invalid ty

[romad]

When I call :

CtMethod cm = ...
cm.insertAfter("if ($_ == null);");

for method which return int[], for ex:

public int[] test() {
 int[] arr = {1,2};
 return arr;
 }

I keep getting " javassist.CannotCompileException: [source error] invalid types for ==" exception.

Is there any way to avoid it?

thank you

I looked into source code and looks like array datatypes are not parsed correctly (int[] interpreted like int and later check for expression parameters doesn't like to have primitive and none primitive types mixed together or something like this)

Anyway, in case somebody would have similar problem, one way to avoid it -
is to wrap return value with $w and assign it to Object obj and use obj instead of $_. Not sure if it will work for all cases but at least should prevent compilation exception.

for ex:

cm.insertAfter("Object obj = (($w)$_); if (obj == null) ... ;");
