[jira] [Updated] (DBCP-417) BasicManagedDataSource does not free connection after transaction is commited

["Balazs Zsoldos (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DBCP-417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Balazs Zsoldos updated DBCP-417:
--------------------------------

    Description: 
When a JTA Transaction is commited, the Managed connection is not available again. The pool is becomes exhausted.

To reproduce:

{code:java}
Jotm jotm = new Jotm(true, false);
JdbcDataSource h2DataSource = new JdbcDataSource();
h2DataSource.setUrl("jdbc:h2:mem:test_mem");
BasicManagedDataSource basicManagedDataSource = new BasicManagedDataSource();
basicManagedDataSource.setTransactionManager(jotm.getTransactionManager());
basicManagedDataSource.setXaDataSourceInstance(h2DataSource);
basicManagedDataSource.setMaxTotal(2);
basicManagedDataSource.setMaxIdle(2);

UserTransaction userTransaction = jotm.getUserTransaction();
userTransaction.begin();
Connection connection = basicManagedDataSource.getConnection();
connection.close();
userTransaction.commit();

userTransaction.begin();
connection = basicManagedDataSource.getConnection();
connection.close();
userTransaction.rollback();

// The managed datasource will block here as there is no available connection
userTransaction.begin();
connection = basicManagedDataSource.getConnection();
connection.close();
userTransaction.commit();
{code}

Set the priority to Blocker as BasicManagedDataSource cannot be used at all with the bug.
