8257809: JNI warnings from Toolkit JPEG image decoding

[prrace]

The fix is to reverse the order of acquisition to get dst before src so that the call to GetArrayLength() comes first.
This also necessitates moving the RELEASE_ARRAYS() call on an error condition to the new "2nd" block.

The new regression test passes on all platforms and all the other headless tests passed too.
So do the automated headful tests.

I always wonder why it is not possible to report such warnings as fatal errors or at least report the exit code as non zero. Probably it is meant to create an enhancement?
