[jira] [Comment Edited] (JCLOUDS-1055) BlobStore.blobExists throws
exception when blob does not exist
[ https://issues.apache.org/jira/browse/JCLOUDS-1055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15097019#comment-15097019 ]

Ok.
When the 404 hits, the ParseSwiftErrorFromHttpResponse parser tries to match the path
/v1/2016-01-12/1cfeb96cccc6569703dcdba64354ee5a-fb66d02f-f2a4-4a4b-90a9-1106b66a014aa
to
^/v[0-9][^/]*/[^/]+/([^/]+)/(.*)
~= /v1/something/container/key
Because "something" is missing (in unit tests, that's 'AUTH_test', the parser fails and throws a generic 404 exception instead of returning false.

> I get exeption when I try to call {{blobExits(container, name)}} with valid container and invalid name. Jclouds [javadoc|https://jclouds.apache.org/reference/javadoc/1.9.x/org/jclouds/blobstore/BlobStore.html#blobExists(java.lang.String, java.lang.String)] does not document this behavior.
