firebird *-xa-ds.xml problem Jboss freezes

[jivkoto]

Hi, I am using jboss 3.2.6 and I am migrating from ms sqlserver 2000 to firebird 1.5.2 (jeybird driver). When i start jboss it freezes. I am wondering why (yes i read first and second first.)
Here is my firebird-xa-ds.xml file


<xa-datasource>
<jndi-name>WORKFLOWDB</jndi-name>
<track-connection-by-tx>true</track-connection-by-tx>
<isSameRM-override-value>false</isSameRM-override-value>
<xa-datasource-class>org.firebirdsql.pool.FBConnectionPoolDataSource</xa-datasource-class>
<xa-datasource-property name="Database">localhost/3050:WORKFLOWDB</xa-datasource-property>
<user-name>SYSDBA</user-name>
masterkey
<!--transaction isolation-->
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
<!--pooling parameters-->
<min-pool-size>10</min-pool-size>
<max-pool-size>500</max-pool-size>
<blocking-timeout-millis>60000</blocking-timeout-millis>
<idle-timeout-minutes>15</idle-timeout-minutes>
<!-- Debugging -->
<track-statements>true</track-statements>
</xa-datasource>


Last message before jboss freezes is:
14:19:28,359 INFO [WORKFLOWDB] Bound connection factory for resource adapter fo
r ConnectionManager 'jboss.jca:service=XATxCM,name=WORKFLOWDB to JNDI name 'java
:/WORKFLOWDB'

This is a firebird issue:

meout (2147483 ms)

.java:313)

I dispair sometimes at java developers inability to read stack traces.
