[jira] [Commented] (IMAGING-319) updateExifMetadataLossless lost the first character of a String

["Stefan Oltmann (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IMAGING-319?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17832282#comment-17832282 ] 

Stefan Oltmann commented on IMAGING-319:
----------------------------------------

Hi [~yangsicheng],

we have a fix for the problem, but we haven't it commited to the sources as we lack a test image for the unit tests.

Is the image you attached to this ticket yours? Do you own the rights to it? If so, would you allow us to add it to the projects sources (for unit tests) under Apache 2 license?

@[~kinow] FYI
