[jira] Commented: (HARMONY-6202) JarEntry.getCertificates() not working with JarEntryStream

["Chris Gray (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-6202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12707699#action_12707699 ] 

Chris Gray commented on HARMONY-6202:
-------------------------------------

Basic problem seems to be that when the current file is a meta-file and the application calls getNextEntry() the current file is not processed in any way, we just skip to the next entry. So the example code passes over the entries for the *.DSA and *.SF files but does not store read in the contents and create entries in the metaEntries map. So when JarVerifier.getCertificates() is called it doesn't find any signatures ...

> Following code fails on Harmony, i.e. prints "No certificates" even though the jar has been signed with Sun's jarsigner tool. Code works on RI 1.4, fails on RI 1.5 (subject of Sun bug report no. 6284489), works on RI 1.6.
