So to summarize so we can close this. I assume that we all agree that
the JNI spec is lacking, and that we should follow the RI as it's
reasonable behavior.
Gregory has added a patch to HARMONY-1156 and I'm going to accept and
apply that.
If there is any opposition, please speak now.

+1 for the following check:
a) offset is negative or
b) len is negative or
c) off + len > buff.length

IMHO our Compatibility guidelines, if the spec is not clear, we
should follow RI. So no matter what happens to the spec(unless it
describe the detail condition of exception-thrown), it is still OK to
follow RI here, am I right?
Ok you didn't

Please correct me if I'm wrong, I thought what you mentioned as
"compatibility guideline" is this[1], as the url shows, it's so far only
classlib compatibility guideline, though I guess most of them makes
sense for VM, but we may need some discussion to decide, let the VM
developers speak for t

This is an interesting problem. The JNI spec is clear that we should
throw an exception when one of the indexes isn't valid, and start =
It looks like that it is possible to get zero bytes even at the very
end of array. IMHO the order of boundary checks makes sense here.

Hi,
As discussed in the former thread, I find that a JNI of DRLVM
(GetByteArrayRegion) differs from RI in passing parameter
(byte[count],count,0). RI (and J9 VM) returns immediately but DRLVM
throws an ArrayIndexOutOfBoundsException.
IMHO
I think we should just fix it in DRLVM, although performance-wise,
wouldn't also fixing in Java make sense too?
As Tim said, raise a JIRA.

Unfortunately, imageio is not implemented yet.

I think this is because winstone will sometimes do a

zero. It's likely that this is swallowed invisibly by IBM JR
