[hibernate-issues] [Hibernate-JIRA] Created: (ANN-677) Blob is null with Postgresql

Blob is null with Postgresql ---------------------------- Key: ANN-677 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-677 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.2.1 Environment: hibernate-3.2.1, hibernate-annotations-3.2.1, postgresql-8.2.5-1.fc7, postgresql-jdbc-8.2.504-1jpp.fc7 and postgresql-8.2-506.jdbc4.jar Reporter: Aaron Luchko Attachments: hibPostgresbug.zip I've found that after a sequence of queries, starting new transactions and clearing the session, a Blob will not be successfully from the database and null will be returned by the InputStream instead. Using the debugger I've followed this into the jdbc code and from what I can tell some message is sent to load the blob but the database replies with an empty set of data which naturally causes the InputStream to read null. I've attached a test case (sorry, no makefile or pom.xml, I just ran it using eclipse) which, for me, replicates the bug. Note I've also used hsqldb and mysql and didn't see the bug with them, only postgresql. thanks, Aaron -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
