> Key: UIMA-4743
> URL: https://issues.apache.org/jira/browse/UIMA-4743
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Affects Versions: 2.8.1SDK
> Reporter: Marshall Schor
> Fix For: 2.9.0SDK
>
>
> (Found by code reading, needs test case) The code for handling long/dbl value
> modified cells while doing delta serialization appears to have a some
> copy/paste kinds of errors. The first (line 583) gets the modified addrs, but
> gets the "short" rather than "long" addrs. The second (line 587) writes the
> address of the modified value using a writeShort, which silently fails if the
> value is > 32767.
> This same kind of error (writing the address as a short) also appears in the
> handling of modifications of shorts (line 570).
> Fixing this will result in writing more bytes to the serialization stream, so
> the streams won't be "compatible". Therefore, do some kind of incrementing
> of versions and serialVersionId values to signal to readers this format
> change. Updating this for client/server pairs will require updates at both
> ends.
