synchronized RMI method call?

[Digital Puer]

In RMI, if I make the remote mehod "synchronized," is it guaranteed
that only one client can enter that method at a time? I read
somewhere that this was not guaranteed (surprisingly).
Thanks for any info.

how could it not?

The calls to the stub in various remotes can proceed to send off their
RMI packets, but the threads will have to line up in the server to
lock that object.

No you didn't, you read that there is no guaranteed relationship between
client threads and server threads in RMI, so as to allow the RMI runtime
to use the same server thread sequentially for multiple client threads
if it so desires. 'synchronized' still does what the language
specification says, though.
