When you serialize a String, it uses DataOutput.writeUTF(), which prefixes the string
with a two-byte representation of the number of bytes in the string. Therefore, the
serialized String is limited to 64K of UTF-8 bytes (not chars). Which is a pretty nasty
bug, but they couldn't figure out how to fix it in a backward-compatible way. I vaguely
recall that they were somehow going to fix this for some JDK release, but I don't
remember which one.
P.S. Thanks for the mailing list help.
