[jira] [Commented] (CODEC-263) Base64.decodeBase64 throw exception

["Benjamin Sproule (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CODEC-263?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17210196#comment-17210196 ] 

Benjamin Sproule commented on CODEC-263:
----------------------------------------

1.15 has been released, so this exception is no longer thrown (unless the `CodecPolicy` is defined as strict). But the `isBase64` function still produces a differing view. Shouldn't it be possible for the `isBase64` function to also care about the `CodecPolicy`?
