Description

class MyString {
    @Delegate String str
}

assert MyString != null

The code above fails with the error below

Caught: java.lang.ClassFormatError: Code attribute in native or abstract methods in class file MyString

It happens because String class has a native intern(). The delegate method that @Delegate adds to MyString continues to be marked native and now has code body added to it, which causes the ClassFormatError.
