>Hmmm ... sorry.
>
>The bug isn't actually in the scheduler or accept() method at all -- it's in exception handling.
>
>My code (designed to run on other machines, but also knowing that Kaffe didn't support reflection) was trying to call a reflection method as follows:
>
> try {
> // call reflection method
> } catch (Throwable t) {
> // call substitute that doesn't use reflection
> }
>
>This caused the thread to crash (but apparently not the VM, however, I haven't fully investigated this). So the program continued to run, but I couldn't get the thread to advance beyond the ServerSocket.accept() method, because the next call was the call above.
>
>Sorry if I sent anyone on a wild-goose chase.
>
>I know that there's a patch out there for reflection; maybe my ISP will go and get it and install it for me (Duane?).

>-- David.
