Javadoc
Notifies subclasses that a new stack map frame is being visited. The
array argument contains the stack map frame types corresponding to the
local variables added with
#newLocal. This method can update
these types in place for the stack map frame being visited. The default
implementation of this method does nothing, i.e. a local variable added
with
#newLocal will have the same type in all stack map frames.
But this behavior is not always the desired one, for instance if a local
variable is added in the middle of a try/catch block: the frame for the
exception handler should have a TOP type for this new local.
