Your code in sub sub2 ... is calling _sub1() without arguments. It should probably look more like: 

    my $self = shift;
    return $self->_sub1();

I'll also point out that prototypes are meaningless when used with OO methods: see perlsub - Prototypes. I'd suggest changing all instances of: 

sub XXX() { ... }

to

sub XXX { ... }
