I have upgraded my Jaybird dependency in Wildfly 10 from Jaybird 2.2.11 to Jaybird 3.0.0-alpha-1. When I try to create a connection I now get the following stacktraces
The first connection after startup (when testing in the admin console):

I use the following module.xml for the Jaybird driver:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.firebirdsql">
<resources>
<resource-root path="jaybird-3.0.0-alpha-1.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
<module name="javax.resource.api"/>
</dependencies>
</module>
NOTE: This question/answer is derived from the bug report JDBC-449
回答1:
At the time of the question, test versions of Jaybird 3 also depended on classes in javax.xml.bind as indicated by java.lang.ClassNotFoundException: javax.xml.bind.JAXBException. This exception causes the loading of the encoding definitions to fail, which then causes the loading of org.firebirdsql.encodings.EncodingFactory$DefaultEncodingFactory to fail. As a result, no connection can be made.
The exception on subsequent attempts is caused by the fact that EncodingFactory$DefaultEncodingFactory could not be loaded.
Note: the dependency on javax.xml.bind has been removed in the final Jaybird 3.0.0 release, so the workaround below is not necessary with the final release of Jaybird 3 and higher (see note below on Jaybird 3.0.4 and higher).
The solution is to add a dependency on javax.xml.bind.api to the dependencies of your Jaybird module:
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.firebirdsql">
<resources>
<resource-root path="jaybird-3.0.0-alpha-1.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
<module name="javax.resource.api"/>
<module name="javax.xml.bind.api"/> <!-- Add this -->
</dependencies>
</module>
Note for Jaybird 3.0.4 and higher
Jaybird 3.0.4 for Java 7 only reintroduced a dependency on JAXB. If possible, switch to the Java 8 version of Jaybird, otherwise apply this solution.
