<h1>Description</h1>
<p>The DbTxn.abort method causes an abnormal termination of the transaction.
The log is played backward, and any necessary recovery operations are
initiated through the <b>recover</b> function specified to
<a href="../api_java/env_open.html">DbEnv.open</a>. After the log processing is completed, all locks
held by the transaction are released. As is the case for
<a href="../api_java/txn_commit.html">DbTxn.commit</a>, applications that require strict two-phase locking
should not explicitly release any locks.
<p>In the case of nested transactions, aborting a parent transaction causes
all children (unresolved or not) of the parent transaction to be aborted.
<p>All cursors opened within the transaction must be closed before the
transaction is aborted.
<p>After DbTxn.abort has been called, regardless of its return, the
<a href="../api_java/txn_class.html">DbTxn</a> handle may not be accessed again.
<p>The DbTxn.abort method throws an exception that encapsulates a non-zero error value on
failure.
<h1>Errors</h1>
<p>The DbTxn.abort method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods.
If a catastrophic error has occurred, the DbTxn.abort method may fail and
throw a <a href="../api_java/runrec_class.html">DbRunRecoveryException</a>,
in which case all subsequent Berkeley DB calls will fail in the same way.
