standardjbosscml-jdbc.xml contains an error in datatype mapping for
Firebird:

<mapping>
<java-type>java.lang.Object</java-type>
<jdbc-type>JAVA_OBJECT</jdbc-type>
<sql-type>BLOB</sql-type>
</mapping>

However, instead it should be:

<mapping>
<java-type>java.lang.Object</java-type>
<jdbc-type>VARBINARY</jdbc-type>
<sql-type>BLOB</sql-type>
</mapping>

or

<mapping>
<java-type>java.lang.Object</java-type>
<jdbc-type>BLOB</jdbc-type>
<sql-type>BLOB</sql-type>
</mapping>


Either fix your standardjbosscmp-jdbc.xml or add appropriate mapping to your
deployment descriptor.
