LOB locks are not released after free().
----------------------------------------
Key: DERBY-3098
URL: https://issues.apache.org/jira/browse/DERBY-3098
Project: Derby
Issue Type: Bug
Components: Store
Affects Versions: 10.3.1.4, 10.2.2.0
Environment: Any
Reporter: Øystein Grøvlen
Assignee: Øystein Grøvlen
When getBlob/getClob is called on the ResultSet, the current row is
locked if the JDBC driver does not cache the entire LOB value in
memory. This is done to prevent the Blob/Clob object from being
changed. Until now, this lock has been held to the end of the
transaction.
JDBC4 introduced free() methods for the Blob/Clob class. The locking
should be changed so that the locks is releases when the Blob/Clob
object is freed.
