> The HsqldbJDBCAdaptor defines the SQL type used for storing a lob as "OTHER". This is wrong in principle, as this type is intended for storing complex serialized object, not specifically lobs. With this type, the JDBC setObject and getObject methods must be used to store and retrieved the object (which is not the case with ActiveMQ).
> The problem has been encountered and reported in TOMEE-233 and elsewhere.
> With HSQLDB version 2.x, the type "BLOB" should be used for maximum storage capacity and minimum memory use by the database engine. This type is supported in all modes of operation, inclusing in-memory and file databases.
> It seems a simple switch from "OBJECT" to "BLOB" in the code should do the job, as the JDBC setBytes and getBytes methods used by the superclass are compatible with the BLOB type.
