Description

When using JavaBinCodec the values of collections are of type ByteArrayUtf8CharSequence, existing field values are Strings so the remove Operation does not have any effect.

The relevant code is located in class AtomicUpdateDocumentMerger method doRemove.

The method parameter fieldVal contains the collection values of type ByteArrayUtf8CharSequence, the variable original contains the collection of Strings
