Error Reading Locks
-------------------
Key: JCR-440
URL: http://issues.apache.org/jira/browse/JCR-440
Project: Jackrabbit
Type: Bug
Components: core
Versions: 1.0
Environment: Ubuntu Linux, MSSQL2000, JackRabbit 1.0
Reporter: Joseph Toth
Using 1.0 with DbFileSystem, SimpleDbPersistenceManager, on MSSQL.
I don't know what is exactly causing this error, but after a session is closed,
a record where FSENTRY_NAME='locks' in the [workspace]_FSENTRY table persists.
The next time a session is open I receive the following stack trace. Should
this 'locks' record be there? If so, is there a bug in the data from the field
'FSENTRY_DATA'?
Any ideas?
Thanks
