Instantiate class in Jasmin
سؤال
I'm trying to instantiate a class in Jasmin like this:
new Ljava/lang/Object;
dup
invokespecial java/lang/Object/<init>()V
This does compile but the class vierifier complains:
"VerifyError: Call to wrong initialization method."
What's the correct way to instantiate a class?
المحلول
Ahh, I found the f***ing problem:
The parameter of 'new' should be the plain qualified name of the type, not it's decorated name. I. e. instead of
new Ljava/lang/Object;
you should write:
new java/lang/Object
The working code is:
new java/lang/Object
dup
invokespecial java/lang/Object/<init>()V

Try with invokespecial java/lang/Object/()V
