Sorry for chiming in late here, but I was wondering-- has the performance impact of this change been measured? Many years ago, the performance impact vs. the apparent severity of the bug at the time held back this fix (using PutField). Of course, both sides of that consideration may have changed since then.
FWIW, the code change looks correct to me. A style nit: I would drop the "= null" initializer on line 1060-- it is a value that should never be read, so let the compiler enforce that (and then you could declare "data" final as well).
P.S. There is a serialization micro-benchmark framework under test/java/rmi/reliability/benchmark
