I don't see anywhere that > this would actually happen currently, but some codecs were written to account > for this correctly; now they're all correct. Updated everything to compute > the correct offset into the underlying array. (I can add a test for this in > TestAllCodecs once #351 is merged). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
