Hello,

I found a problem in windows/native/java/io/io_util_md.c, method
handleRead(). The return type of the method is size_t, which is defined
as unsigned int. However we see the method would return negative values
while it meets some error. This may be a problem as the API comsumer and
later developer may have misunderstand it. I suggest modify it to
ssize_t (or SSIZE_T as it is on windows).
Any comments?

I suspect this just haven't been noticed before. I checked the pre-OpenJDK history and these handle* functions have been returning size_t since the code was changed from using C runtime functions to win32 functions (in 2003). I don't think we have any resulting bugs but it should be cleaned up so I'll create a bug to track it. I see there are a few other places that have the same issue.

Thanks Alan. Would you please tell me the bug number?
