Yeah hash comparison on writes is a bit of overkill. If you can't rely
on what is written to disk to actually be written to disk we are all in
major trouble!
Also, java handles exceptions for permissions, out of disk space, etc,
pretty well. just try, catch with appropriate handling as per your
application needs...
Java 7 brings a lot of enhancements in nio2 also, so even less code to
write, or you could use commons IO like you suggested...
I think clob encoding is also up to the user application. If it was me I
would just do a binary copy and leave it in the source encoding, but it
really depends on what you are trying to do...

Well, so far it's not a popular feature request.

Seems easy enough.
Writing such *really well coded* function in Java could be a job
for experienced Java programmer - to handle all Exceptions like
target directory permissions, free space size, encoding of CLOB,
check of correctness of writing using comparison of SHA-1 (MD4.
MD5) hash between file content and database LOB etc. Or to use
some File IO like one from Apache. So writing it *once and well*
for all in H2 as SQL function should be more effective and
trustworthy, moreover in case, than FILE_READ already exists. That
is my humble opinion.
