Sergey Mashkov updated BCEL-170:
--------------------------------
Attachment:
BCEL-170_Type_getArgumentTypes()_throws_ClassFormatException.patch
I recommend the following patch to fix ClassFormatException.
The main idea is that we have to consider generics in the signature during
parsing.
To get generics work with Type it should be discussed later.
> Type.getArgumentTypes() throws ClassFormatException: Invalid method
> signature: >;)
