----------------------------------
Summary: [Java Broker, BDB] Close Cursor when
LockConflictException is thrown
Key: QPID-7684
URL: https://issues.apache.org/jira/browse/QPID-7684
Project: Qpid
Issue Type: Bug
Components: Java Broker
Affects Versions: qpid-java-6.1.1, qpid-java-6.0.6, 0.32, qpid-java-7.0
Reporter: Lorenz Quack
Currently, when a LockConflictException is thrown we retry the operation.
However the retry logic does not adhere to the rules outlined in the BDB JE
documentation, specifically we do not close and recreate the Cursor.
To quote the
[documentation|https://docs.oracle.com/cd/E17277_02/html/java/com/sleepycat/je/LockConflictException.html]:
{quote}If a lock conflict occurs during a transaction, the transaction may be
retried by performing the following steps. \[...\]:
# Close all cursors opened under the transaction.
# Abort the transaction.
# Begin a new transaction and repeat the operations.
{quote}
The impact of not doing this is unclear.
