commons-dbcp of version 1.3 / 1.4
            Reporter: an envy guest


When using IBM JDK 6+ and trying to build commons-dbcp, these tests fail:

org.apache.commons.dbcp.managed.TestBasicManagedDataSource
org.apache.commons.dbcp.managed.TestManagedDataSourceInTx

with error:

java.sql.SQLException: Connection does not have a registered XAResource null, UserName=null,
null
	at org.apache.commons.dbcp.managed.TransactionRegistry.getXAResource(TransactionRegistry.java:81)
	at org.apache.commons.dbcp.managed.TransactionContext.setSharedConnection(TransactionContext.java:88)
	at org.apache.commons.dbcp.managed.ManagedConnection.updateTransactionStatus(ManagedConnection.java:131)
	at org.apache.commons.dbcp.managed.ManagedConnection.<init>(ManagedConnection.java:55)
	at org.apache.commons.dbcp.managed.ManagedDataSource.getConnection(ManagedDataSource.java:76)
	at org.apache.commons.dbcp.managed.TestManagedDataSource.getConnection(TestManagedDataSource.java:53)
	at org.apache.commons.dbcp.TestConnectionPool.newConnection(TestConnectionPool.java:81)
	at org.apache.commons.dbcp.managed.TestManagedDataSourceInTx.testMaxActive(TestManagedDataSourceInTx.java:102)

When used in conjunction with OpenEJB 3.1.4 examples, the error is the same.

The problem disappears when switched to Oracle JDK 1.6.24 (so, all tests are passed and OpenEJB
examples are working).

I beleive this has something to do with differences in java.lang.ref.WeakReference implementations
between IBM and Oracle JDKs, which was already discussed here:
