==================== Summary ====================

Name: Files-dtl.184
Author: dtl
Time: 24 October 2019, 10:15:34.856587 pm
UUID: cfa02841-644b-49cb-b3f2-a0eb1b36707b
Ancestors: Files-pre.183

Provide error handling for #adoptInstance in StandardFileStream>>binary to provide pre-Spur behavior when running on a V3 image. Prior to Spur, class ByteArray cannot adopt an instance of ByteString, so use #asByteArray instead.

Resolves the only remaining difference for package Files when running on either Spur or V3 images. The packages with significant Spur/V3 differences (excluding unit tests) are now Collections, Compiler, Kernel, and System. See www.squeaksource.com/TrunkUpdateStreamV3 for verification.
